The HMP155A is an air temperature and relative humidity (RH) sensor that provides reliable measurements for a wide range of applications. It can be used as part of a weather station system or as a single instrument. It r...

The HMP45C is a rugged, accurate temperature/RH probe manufactured by Vaisala Inc. The probe uses a HUMICAP capacitive polymer H chip to measure relative humidity over the 0 to 100% RH range. A PRT measures temperature o...

The HMP50 is a temperature and relative humidity sensor manufactured by Vaisala. It measures air temperature with a 1000 ohm platinum resistance themometer (PRT), and RH with a capacitive chip. Features PRT used for temp...

The CS215 is temperature and relative humidity sensor manufactured by Campbell Scientific Ltd. This probe uses a Swiss-made digital humidity and temperature element that provides good measurement accuracy and stability. ...

FW/ENC Fine Wire Thermocouple Carrying Case The FW/ENC Carrying Case holds four probes and is required to ship thermocouples. Probes returned to Campbell Scientific for repair without this case will be shipped to the cus...

The FW3 Fine Wire Thermocouple is typically used to measure atmospheric temperature gradients or fluctuations. The small mass of the thermocouple is less susceptible to solar loading; therefore, a radiation shield is not...

The FW1 Fine Wire Thermocouple is typically used to measure atmospheric temperature gradients or fluctuations. The small mass of the thermocouple is less susceptible to solar loading; therefore, a radiation shield is not...

The FW05 Fine Wire Thermocouple is typically used to measure atmospheric temperature gradients or fluctuations. The small mass of the thermocouples is less susceptible to solar loading; therefore, a radiation shield is n...

The ASPTC is a type E thermocouple housed in a white, elongated radiation shield. The radiation shield reduces solar loading on the thermocouple by drawing air across the measurement junction with a fan. The radiation sh...

The 43347 probe is typically used in air quality applications to obtain the delta temperature. Air temperature is measured at 2- and 10-meter measurement heights to determine atmospheric stability as required by the EPA ...
