44550 Pocket Humidity/Temperature Pen
10134
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.

CO2 Meter
10549
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.

TR21-B Resistance Thermometer
2887
The WIKA TR21-B resistance thermometer provides temperature measurement in sanitary applications and can be used for the measurement of liquid and gaseous media in the range of -30 … 150°C (-22 … +302 °F). For application in hazardous areas, intrinsically safe versions are available. To integrate it into the process, the WIKA TW61 thermowell is directly orbitally welded into a pipeline. The connection ends are straight and prepared for orbital welding. The process connections meet the stringent requirements, in terms of materials and design, of hygienic measuring points. All electrical components are protected against moisture (IP67 or IP69K). The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the PC configuration software WIKAsoft-TT. Measuring range, damping, error signalling per NAMUR NE43 and TAG no. can be adjusted. For easy calibration or maintenance, the sensor is removable without having to break into the process or disconnect the electrical connection. Thus hygiene risks can be minimised, and downtimes can be reduced. The spring loading, integrated into the union nut, guarantees the contact between the sensor tip and the bottom of the thermowell and thus ensures a short response time and lasting high accuracy. Insertion length, process connection, sensor and connection method can each be selected for the respective application within the order information. The electrical connection is made via an M12 x 1 circular connector. For applications requiring the sterilisation of the instrument in autoclaves, an especially temperature-resistant instrument version is available.

TR21-C Resistance Thermometer
2890
The WIKA TR21-C resistance thermometer provides temperature measurement in sanitary applications and can be used for the measurement of liquid and gaseous media in the range of -30 … 250°C (-22 … 482°F). For application in hazardous areas, intrinsically safe versions are available. These thermometers are fitted with process connections that meet the stringent requirements, in terms of materials and design, of hygienic measuring points. All electrical components are protected against moisture (IP67 or IP69K). The resistance thermometer is available with direct sensor output or integrated transmitter, which can be configured individually via the PC configuration software WIKAsoft-TT. Measuring range, damping, fault signal per NAMUR NE43 and TAG no. can be adjusted. The welded junction between the thermowell and the flange makes the use of a sealing as additional material in those areas redundant which are in contact with the product. Through the compact design, this resistance thermometer is designed specifically for operation in applications with limited mounting space. Insertion length, process connection, sensor and connection method can each be selected for the respective application within the order information. The electrical connection is made with an M12 x 1 circular connector. For applications requiring the sterilisation of the instrument in autoclaves, an especially temperature-resistant instrument version is available.
