Professional environmental meter

The Triplett RHT32 HygroThermoPsychrometer is a handheld instrument for HVAC technicians and facilities staff who need simultaneous temperature, humidity and dew-point readings. Its precision capacitance sensor and thermistor deliver 0.1 percent humidity resolution and ±3 percent RH accuracy across the 10 to 90 percent range. The transparent housing lets users confirm sensor condition at a glance. Data-hold freezes the display for recording in tight spaces.

Measurement range and limits

Dew-point coverage spans −90.4 °F to 122 °F, giving ample headroom for sub-zero refrigeration work and high-temperature commercial systems. Response time is 60 seconds, so readings stabilise quickly during walk-through surveys. The meter does not log data internally, so technicians must record values manually or pair it with an external logger for trend analysis. Accuracy degrades outside the stated humidity band.

Build integration and power

Two AAA batteries are included and power the unit for routine field sessions. No data-logging function means no software setup or cable management on site. The compact form fits in a tool pouch alongside manifold gauges and leak detectors. Buyers needing onboard memory, wireless transfer or NIST-traceable calibration should specify a different model.

Questions about this item

Will the RHT32 work with my existing HVAC gauges that use standard probe ports?

The RHT32 is a standalone hygrometer-psychrometer with an onboard precision capacitance sensor and thermistor; it does not have probe ports or an interface for connecting external HVAC gauges.

How can I verify the RHT32 is reading correctly after I install the batteries?

After inserting the two included AAA batteries, the display shows humidity with 0.1% resolution and temperature; a reading within the ±3% RH accuracy band between 10% and 90% RH and a dew point between -90.4°F and 122°F indicates normal operation.

What comes in the box with the RHT32 and what must I buy separately?

The package includes the RHT32 unit and two AAA batteries for immediate use; no additional accessories or sensors are required for basic temperature, humidity and dew-point measurements.
