Hygrometer: Digital Protimeter Hygromaster 30 to 100% RH (BLD7700) with HygroStick & Belt Holster

The Protimeter HygroMaster is an easy to use hygrometer with built in data logging capability. The HygroMaster is a hand-held instrument for taking spot measurements and for logging humidity and temperature values. Quick measurements of relative humidity, dew point, mixing ratio (grains per pound/parts per million by weight) and ambient temperature are shown on a split display at the touch of a button. Surface temperature measurements can also be measured with an optional surface temperature sensor, making this instrument especially suitable for condensation risk assessment and diagnosis.

• Versatile hygrometer that measures humidity, air temperature and Dew Point
• Excellent for taking spot measurements and for logging humidity and temperature values
• measurements of relative humidity, dew point, mixing ratio and ambient temperature are shown on a split display at the touch of a button
• Surface temperature measurements can also be measured with an optional surface temperature sensor
• Especially suitable for condensation risk assessment and diagnosis
• The HygroMaster has a data-logging mode to meet this requirement. The user sets the instrument to record measurements as required and leaves it in place for the required period of time. The memory contents are then downloaded to a PC using optional software where the logged measurements are displayed in tabular and graphical form.
• Two types of humidity probes are offered for use with the HygroMaster, the Hygrostick (POL4750) and the QuickStick (POL8750)
  • The HygroStick (POL4750) in optimized for measuring humidity in the 30 to 100%rh range and may be used with Protimeter humidity sleeves that are used when measuring the equilibrium relative humidity of solid walls and floors.
  • The QuickStick (POL8750) is a general purpose sensor with a range of 1 to 100%rh making more suitable for general air quality applications, including outputs from dehumidifiers and HVAC systems.

• Nominal measurement range: 30 to 100%
• %RH Accuracy: In the range of 30 to 40% is approximately ±2.5%RH
• %RH Accuracy: In the range of 41 to 98% is approximately ±1.75%RH
• Temperature measurement range: -10 to 50°C (15 to 120°F)
• Power: (1) 9v battery

Supplied with:

• Instruction manual
