Thermohygrometer Series Operating Instructions (TASI622_622A_622B_622C)
Operating Instructions for Teans Thermo-Hygrometer Series, which is used for the following models of Teans Thermo-Hygrometers: TASI622_622A_622B_622C
Introduction
This product is a hand-held, easy-to-use, and solidly digital thermometer and hygrometer, which is specially designed for one-handed operation . The temperature measurement uses a thermistor and K-type thermocouple as the temperature sensor, and the relative humidity measurement uses a capacitance variable polymer humidity sensor as the sensor .
Electrical Specifications
K type thermocouple wire
Temperature unit: °C Celsius or °F Fahrenheit, selectable by the user .
Measuring range: -50°C to 1000°C, (-50°F to 1832°F)
Resolution: 0.1°C or 0.2°F
Accuracy: Specifications for the temperature and humidity meter operating within one year at 18°C to 28°C (64°F to 82°F), excluding the error of the K-type thermocouple wire probe .
±(0.1% of reading + 1°C) at -50°C to 1000°C
±(0.1% of reading + 2°F) at -50°F to 1832°F
±(0.05% of reading + 1.4°F) at -58°F to -328°F
Temperature sensor: Thermistor temperature sensor
Measuring range: 0°C to 60°C, (32°F to 140°F)
Resolution: 0.1°C/°F
Accuracy:
±2°C at 0°C to 10°C
±0.5°C at 10°C to 45°C
±2°C at 45°C to 60°C
±4°F at 32°F to 50°F
±1°F at 50°F to 113°F
±4°F at 113°F to 140°F
Relative humidity:
Sensor: capacitive humidity sensor
Measuring range: 0% to 100% RH
Accuracy:
±2.5% at 25°C(77°F), 10% to 90% RH
±5% at 25°C(77°F), 0% to 10% RH, 90% to 100%RH
The time required for the sensor to respond to 90% of the humidity range to be measured: about 60 seconds.
Sensor hysteresis (humidity changes from 10%RH to 90%RH
Back to 10%RH): ±1.0%RH.
Temperature Coefficient: From 0°C to 18°C and 28°C to 50°C, the accuracy of the specification changes by one-tenth for every 1°C increase or decrease .
Input protection: The maximum input voltage of the temperature input socket is 24V DC voltage or AC voltage.
Temperature input seat: It can be inserted into a standard small thermocouple plug (the center distance between the two terminals is 7.9mm).
