Measurement of non-electrical size

DE-3009 Thermo-Hygrometer.

The DE-3009 Digital Thermo-Hygrometer with Data Logging is a dual-channel meter that allows you to measure ambient temperature and humidity in one channel, and temperatures in the range of -200 ºC to +1370 ºC via a K-type probe in the other channel. Ambient parameters in the ranges of -20ºC +60ºC for temperature and 1% - 99% for relative humidity are measured by a combined thermo-hygro sensor connected to the meter via a mini DIN connector. A clear LCD display with 2-second sampling rate displays all three measurements simultaneously, with the ability to toggle between the central display (9999 count) and the secondary display. Additionally, a portion of the display is dedicated to the real-time clock. In other modes, this field can display a stopwatch or the reference temperature in a relative measurement. The meter can store 10 combined measurement results, along with the time from the first measurement. When reading the stored measurement data, the meter simultaneously displays three values: maximum, minimum, and average. It features a splash-proof housing, a high-quality membrane keypad, an RS-232 port, and an external power supply socket. The kit also includes software for communication with a computer.

DE-3003 Single-Channel Thermometer DE-3004 Dual-Channel Thermometer

The following meters are used to measure temperatures in the range of -50 ºC ~ +1300 ºC: DE-3003 (single-channel) and DE-3004 (dual-channel). The meters, equipped with K-type bead probes with a 1.2 m Teflon-insulated cable (260 ºC), achieve an accuracy of 0.3% of the measured value + 1 ºC in the temperature range of -50 ºC to +1000 ºC. The user can select the instrument scale between Fahrenheit and Celsius and the corresponding display resolution of 0.1 ºC / 0.1 ºF or 1 ºC / 1 ºF. The front panel of the meter features a calibration knob, and the measurement inputs are equipped with overload protection (60 Vdc or 24 Vrms). The dual-channel version of the meter also has the ability to display the difference between the values ​​obtained from both channels. The meter housings are protected by a rubber cover.

DE-33 Wireless Dual-Channel Thermometer with Type K Probe.

Wireless two-channel meter with a K-type probe for temperature measurement DE-33. The device consists of two modules – a measuring/transmitting module and a receiver with a display. It has a measurement range from -200 to +1370ºC and internal memory for storing measurement results and their times. Data from the measuring section to the display is sent every 3 minutes, and the maximum distance between the modules can be 100m. The meter signals when the set temperature range is exceeded and can communicate with a computer. Measurement accuracy ranges between 0.2 and 0.5%.
