Protimeter Psyclone BLD7800

Highly durable and functional hand held thermo-hygrometer

Protimeter MMS Protimeter Psyclone - Humidity Meter Watch the video

The Protimeter Psyclone moisture meter is designed to measure relative humidity and temperature in a wide range of environments and applications. The GE Protimeter Psyclone thermohygrometer measures relative humidity with psychometric measurements, along with temperature. One button enables Start, Hold and OFF operation, and four arrow keys allow you to set up and change the measurements shown on the LCD screen. An optional surface temperature probe enables users to determine if condensation is present.

Fast Response for a Variety of Measurements

When measuring humidity and temperature in a range of different environments, it is essential that you have an instrument that responds quickly to those changes. The Psyclone thermo-hygrometer not only responds quickly, it also measures a variety of parameters:

  • Percent relative humidity (% RH)
  • Temperature (°F or °C)
  • Grains per pound (GPP)
  • Gram/kilograms (g/kg)
  • Dew point temperature (°F or °C)
  • British thermal units/pound (BTU/lb)
  • Wet bulb temperature (°F or °C)
  • Parts per million by weight (ppmw)
  • Kilocalorie/kilogram (Kcal/kg)
  • Surface temperature (°F or °C)
  • Surface proximity to dew point (°F or °C)

Flood Damage Restoration

Accurately measuring the atmospheric conditions during building dry down is key to ensuring drying equipment is used efficiently. Psyclone rapidly responds to changes in humidity and temperature while calculating the specific humidity readings to reduce errors and save time. During hot air drying, Psyclone also calculates enthalpy to maximize equipment performance.

Building Surveys

Psyclone is ideal for condensation risk assessment and diagnosis applications. Using the optional surface temperature sensor, the meter can display actual surface temperature and dew point temperatures. This feature helps determine whether a moist surface is due to condensation or other sources. For example, negative temperature differences confirm condensation, whereas positive
differences confirm condensation is not occurring.

HVAC/R System Validation

Psyclone is specifically designed with time saving features for the HVAC technician or building maintenance professional concerned with HVAC performance validation. Using the percent relative humidity (% RH) and temperature measurements as inputs, Psyclone calculates the necessary derived psychometric parameters, such as enthalpy, dew point, and wet bulb temperatures needed to assess and troubleshoot the performance and energy efficiency of any HVAC system.
