Innovative Instruments
Innovative Instruments covers two distinct product lines supplied by MetSensor UK: RTD temperature calibrators for metrology and process verification, and acoustic drone detection sensors for airspace monitoring. Both are manufactured by Zata IoT and supplied in the UK through MetSensor UK on a quote basis.

Products in this category
ZTC100 RTD Temperature Calibrator
ZTC100
The ZTC100 is an RTD temperature calibrator that uses the PT100 platinum resistance measurement principle to verify and calibrate temperature sensors. It communicates over RS485 or RS232 and runs from AC 220V or DC 12/24V at under 2W. MetSensor UK supplies the ZTC100 in the UK as the official Zata IoT reseller, on a quote basis.
ZD-EAR Acoustic Drone Detection Sensor (UAV Direction Finder)
ZD-EAR
The ZD-EAR is an acoustic drone detection sensor that locates UAVs by analysing their sound signature across a microphone array of up to 208 channels. It detects at a stated range of 0.1 to 500 m with a 0.1 second response time and includes an integrated 13 MP camera for visual confirmation. MetSensor UK supplies the ZD-EAR in the UK as the official Zata IoT reseller, on a quote basis.
What this category covers
Innovative Instruments is a category for specialised measurement and detection equipment that does not fit standard environmental sensor lines. It currently contains two subcategories: Temperature Calibrator and Acoustic Drone Detection. These products serve different buyers and different applications, but both are precision instruments that require accurate specification matching before purchase.
The Temperature Calibrator subcategory contains the ZTC100 RTD Temperature Calibrator, an instrument used to verify and calibrate PT100 platinum resistance thermometers. The Acoustic Drone Detection subcategory contains the ZD-EAR, a microphone-array sensor used to detect and locate unmanned aerial vehicles (UAVs) by their acoustic signature.
How RTD temperature calibration works
A temperature calibrator generates or measures a known temperature reference so that a separate temperature sensor can be checked against it. The ZTC100 works on the PT100 measurement principle, using a platinum resistance element whose electrical resistance changes predictably with temperature. This resistance-to-temperature relationship is the basis for RTD (Resistance Temperature Detector) calibration.
The calibrator communicates over RS485 or RS232, which allows it to be integrated into automated calibration benches or read out via standard industrial interfaces. It runs from AC 220V or DC 12/24V at under 2W, so it can be deployed on mains power or low-voltage DC systems in the field or in a lab.
How acoustic drone detection works
Acoustic drone detection identifies UAVs by picking up the sound they generate, rather than by radar or radio-frequency scanning. The ZD-EAR uses a microphone array of up to 208 channels to capture sound across a 20 Hz to 20,000 Hz frequency range and a sound pressure level range of 28 to 132 dB. By comparing the arrival time and intensity of sound across the array, the system calculates a direction of arrival, which is used to localise the source.
The ZD-EAR also carries an integrated 13 MP camera with a 95° (H) x 76° (V) field of view and up to 6x digital zoom, so an operator can visually confirm an acoustic detection. Data connectivity is handled over Wi-Fi (802.11a/b/g/n/ac) and Bluetooth 5.2.
Key specifications to compare
For a temperature calibrator, the specifications that matter most are measurement range, resolution, accuracy, and communication interface. These determine whether the instrument can calibrate the sensors used on your process and whether it will integrate with existing calibration or SCADA systems. Because published figures for the ZTC100 differ slightly between the manufacturer's product page and subcategory page, buyers should confirm the exact range, resolution, and accuracy figures for their intended use case at the quotation stage.
For an acoustic drone detection sensor, the specifications that matter most are detection distance, response time, microphone channel count, and dynamic range. The ZD-EAR is rated for a detection distance of 0.1 to 500 m with a 0.1 second response time, figures that determine how quickly and from how far the system can flag an incoming UAV.
Typical applications and industries
The ZTC100 is used by metrology institutions, meteorological services, railway operators, and scientific research organisations that need to verify PT100 thermometers against a stable reference. The manufacturer states the unit does not require recalibration for 10 years, which is relevant for organisations planning long-term calibration schedules.
The ZD-EAR is used in military applications, airport no-fly zone monitoring, border defence, and other government no-fly zone enforcement, as well as general defence systems that require passive acoustic detection of UAVs.
How to choose between models in this category
Because the two subcategories serve unrelated purposes, the first choice is which subcategory matches your requirement: temperature calibration or drone detection. Within Temperature Calibrator, the ZTC100 is currently the only model listed, so selection comes down to confirming its measurement range, resolution, and accuracy meet your calibration standard. Within Acoustic Drone Detection, the ZD-EAR is currently the only model listed, so selection comes down to confirming detection distance, response time, and environmental operating range (-20°C to 50°C, 10-80% humidity, non-condensing) suit your deployment site.
Buying through MetSensor UK
MetSensor UK is the official UK reseller of Zata IoT instruments, not the manufacturer.

Pricing, lead time, and any project-specific configuration are confirmed once we understand your application, so contact MetSensor UK with your requirements to receive a formal quote.
Frequently asked questions
What products are in the Innovative Instruments category?+
Two subcategories: Temperature Calibrator, which contains the ZTC100 RTD Temperature Calibrator, and Acoustic Drone Detection, which contains the ZD-EAR Acoustic Drone Detection Sensor.
Who manufactures these instruments?+
Both instruments are manufactured by Zata IoT. MetSensor UK is the official UK reseller and does not manufacture the products.
Does the ZTC100 need regular recalibration?+
The manufacturer states no recalibration is required for 10 years, though buyers should confirm this against their own quality or compliance requirements.
What does the ZD-EAR detect and how far?+
It detects UAVs by their acoustic signature using a microphone array, with a stated detection distance of 0.1 to 500 m and a response time of 0.1 s.
Can the ZTC100 be integrated into an automated calibration system?+
Yes. It communicates over RS485 or RS232, which supports integration with automated calibration benches or industrial monitoring systems.
What environmental conditions can the ZD-EAR operate in?+
It is rated for -20°C to 50°C operating temperature and 10-80% humidity, non-condensing.
How do I get pricing for these instruments?+
Pricing is quote-based. Contact MetSensor UK with your application details and we will confirm price and lead time as the official UK reseller.
Why do the ZTC100 specifications vary between pages?+
The manufacturer's product page and subcategory page state slightly different range, resolution, and accuracy figures. Confirm the exact figures relevant to your application when requesting a quote.
