Portable Relative Humidity Meters

HI93640 Compact Thermohygrometer with Built-in Sensor by Hanna Instruments

HI 93640 is a compact, portable and versatile thermo-hygrometer that monitors relative humidity, anywhere. This simple to use meter is ideal for the HVAC field.

The built-in thin-film capacitance sensor assures accurate humidity measurements from 10 to 95% RH with a resolution of 0.1%.

Designed to be operated with just one hand, the compact housing fits easily in your palm. The design of the rubber keys resists the ingress of dust and protects the instrument from accidental splashes.

A sintered cap can be placed on the sensor shaft for protection in dusty environments. If faster response is desired, the cap can be removed.

The HI 93640 is equipped with BEPS (Battery Error Prevention System) which alerts the user in the event that low battery power could adversely affect readings.

• Portability and simplicity
• Low battery indicator
• Dual temperature range
• BEPS and low battery warning

Order Information:

HI 93640 is supplied with built in RH sensor, protective sintered cap for RH sensor, battery and instructions.

HI9565 Thermohygrometer with Dew Point and Calibration Data-Logging Probe by Hanna Instruments

HI 9565 is a portable thermohygrometer designed to provide peak performance in harsh environments. For poorly lit areas the HI 9565 features a backlit LCD.

In addition to RH and temperature, HI 9565 will display the dew point with the press of a button. The dew point indicates the presence of water vapor in the air at a given temperature. With this feature HI 9565 permits quick and effective environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms and laboratories.

This instrument also features a HOLD button to freeze readings on the display for manual recording and BEPS (Battery Error Prevention System) which alerts the user in the event that low battery power could adversely affect readings.

HI 70602 RH probe features a built-in microchip that can store calibration data. When the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument.

HI 9565 features auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and online help to indicate anomalies and direct procedures.

• Backlit LCD
• Auto shut-off
• HOLD button
• BEPS and low battery warning
