0...550°C - -10...50°C

The Extech 44550 is a pen-style humidity and temperature meter. Featuring a dual LCD for simultaneous display of relative humidity and Temperature (°C/°F switchable). The 44550 measures humidity from 20 to 90%RH and temperature from -10 to 50°C with ±5%RH; ±2°F, ±1°C accuracy. Because of its pocket size, the 44550 is ideal for quick and reliable measurements at any location. Max/Min memory functions for display of highest and lowest readings for both measurements. Complete with pocket clip and one LR44 button battery.

The CO2 Meter for indoor air quality detection detects Carbon Dioxide (CO2), temperature (Celcius) and humidity. The CO2 Meter combines real-time monitoring of Carbon Dioxide (CO2) with temperature and humidity on an easily read LCD. Four types of smiley faces indicate the indoor air quality; 400ppm – 1000 ppm (green) 1001 ppm to 2000 ppm (yellow) 2001 ppm – 3000 ppm (orange) 3001 ppm – 5000 ppm (red) This CO2 Meter is made for indoor applications such as office buildings, schools, restaurants, hospitals, or vessels. With the Carbon Dioxide meter, you can detect when ventilation in a room is necessary to prevent aerosols from spreading through the room. The large and easy to read LCD shows you the CO2 level in ppm. The CO2 Meter helps you improve the overall air quality and prevent potentially COVID-19 from spreading. The automatic calibration function on the Meter makes the device as goods as maintenance-free. When turned on for the first time, a 24-hours calibration cycle will be started. Do not switch the device off within these 24 hours. Set alarm After turning on the device, the current CO2 level of the Meter will be shown. You can manually set an alarm of any ppm level between 800 and 2000 ppm. When the carbon dioxide level of the alarm point is reached, a loud beep sound will be made.

The TUVO Instruments PT100 resistance thermometer, or as some say pt100 temperature sensor, is available in customer-specific lengths variating between 40 and 400mm. The TUVO Instruments PT100 resistance thermometer is a premium Dutch made resistance thermometer capable of measuring temperatures in marine or industrial applications between 0°C and +550°C. The pt100 sensor is available in a 3-/4-wire version or even 6-/8-wire version. If preferred a transmitter can be instaled in the aluminium B-head of the PT100 temperature sensor. Resistance thermometers are particularly suitable for those applications in which the metal sensor tip is mounted directly into bored holes (e.g. in machine components) or straight into the process for any application with no chemically aggressive media or abrasion. The TUVO Instruments PT100 resistance thermometer lends itself ideally for use in bearings, machine building, engines, pipelines and vessels. All TUVO Instruments pt100 temperature sensors are individually made to customer specifics. As a distributor of TUVO Instruments, this means that you could give us your wishes regarding the temperature sensor and it will be handcrafted in Rotterdam within 3 to 5 business days. All pt100 thermometers are made under strict circumstances with only high-quality materials available. This so durability and reliability can be guaranteed.
