Hand Held Thermo-Hygrometers RH/C and dewpoint meter

The Hanna HI-9565 portable thermo-hygrometer is designed to measure relative humidity and temperature in difficult environments and poorly lit areas.

A particularly fast response time offering near instant results for relative humidity plus the added advantage of being able to measure dewpoint make this instrument ideal for rapid monitoring in controlled micro-climates.

Ideal for

• Measuring in restricted locations such as air conditioning ducts
• Monitoring microclimates in greenhouses
• Maintaining controlled climate in libraries and museums
• Clean rooms and laboratories

Key features

• Fast response time
• Probe is attached to a long 1m cable permitting improved access for testing in awkward conditions
• Dewpoint can be measured and displayed at the touch of a button - particularly useful in microclimate testing
• Backlit LCD display provides good visibility in low ambient light levels - ideal for museums and libraries
• HOLD key freezes readings on display allowing time to record data
• Robust casing with splashproof keyboard
• Temperature readout available in either °C or °F
• Fast response probe incorporates microprocessor for calibration data storage

Main benefits

• Fast response with direct readout of relative humidity without the need for reference charts
• Includes automatic dewpoint calculation
• Built-in temperature sensor with auto shut-off
• Designed to aid monitoring in restricted spaces

A microchip built into the RH probe, HI 70602, 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. 

The instrument features auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and on-line help to indicate anomalies and direct procedures. 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 useful and rapid environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms and laboratories.
