Structured to assist in consistent experimental procedures, the compact yet comprehensive Thermohygrometer Testo 622 is designed for precise measurement of temperature, humidity, and air pressure within laboratory environments. Weighing just 240 grams, this device features a dew point sensor and an easily readable display that shows current measurements along with the date and time. It also includes visual alarms that activate when preset limits are exceeded, allowing for immediate intervention. Additionally, the Testo 622 offers minimum and maximum functions, ensuring accurate record keeping. Powered by four Mignon/AA 1.5V batteries, it boasts high precision with a temperature accuracy of ±0.4°C, air pressure accuracy of ±3hPa, and relative humidity accuracy of ±2% at +25°C (10 to 90%) ±3% (outside). Its temperature measuring range extends
