The HHC200 series rugged environmental monitors are designed to meet most on-site environmental monitoring needs. They are tough and durable, with built-in bumpers and a unique metal sliding cover to protect them when not in use, or when in a toolbox or truck seat. The units are also compact and can be easily carried on a tool belt or in a tool bag, measuring just 1" x 2" x 5.25". 

Temperature-wise, the HHC201 is a dual-input thermocouple thermometer with 0.1% accuracy, auto-ranging with 0.1° or 1° resolution, and comes with 2 K-type thermocouples. Its measurement range is -76 to 2500°F or -100 to 1372°C. The backlit triple display shows T1, T2, and T1-T2. Hold, min, max, max-min, and average temperature functions are also available.

The HHC210 is an infrared thermometer equipped with laser aiming and a 6:1 distance-to-spot ratio. Emissivity is adjustable from 0.1 to 1.00. Measuring range: -22 to 1022°F (-30 to 550°C). Accuracy: ±2°C below 100°C; ±2% of reading at 100°C. Operating ambient range: -4 to 140°F. Backlit display shows infrared temperature, ambient temperature and temperature difference between the two. Hold, Minimum, Maximum, Max-Min and Average functions are selectable.

Pressure Meters

HHC280 Low Pressure Manometer

Measures gauge pressure or differential pressure from 0 to 40 inH₂O (1.45 psi). Suitable working medium: clean, non-conductive gas. The backlit display shows P1 gauge pressure and P1-P2 differential pressure. Pressure readings can be displayed in 8 engineering units; compatible with pitot tubes for air velocity measurement. Hold, Min, Max, Max-Min and Average functions are available.

HHC281 Absolute Pressure Meter

Measures absolute pressure (referenced to absolute zero). Supports eight engineering units plus altitude display in meters and feet. Absolute pressure range: 4.35 psia to 17.3 psia. The backlit display shows pressure or altitude. Hold, Min, Max, Max-Min and Average functions are available.

Airflow / Humidity / Dew Point / Wet Bulb / Wind Chill

HHC261 Precision Hygro-Anemometer

Designed for outdoor or laboratory environmental measurement. It measures air velocity up to 4000 ft/min, air temperature and humidity, and calculates dew point, wet bulb and wind chill values. Hold, Min, Max, Max-Min and Average functions are available.

Light Measurement

HHC230 Environmental Light Meter

Measures illumination in lux or foot-candles. Used to set lighting levels for various workstations to optimize efficiency.

Reference illumination examples: General office: 1500–2000 lux; Meeting room: 300–700 lux.

Hold, Min, Max, Max-Min and Average functions are available.

Non-Contact RPM

HHC250 Non-Contact Tachometer

Measures rotational speed up to 99,999 rpm. Automatically switches to 0.1 rps resolution at low speeds for non-contact measurement. Attach a small strip of reflective tape on rotating equipment. A red LED on the instrument marks the aiming point to ensure accurate readings. Hold, Min, Max, Max-Min and Average functions are available.

The HHC200 Series digital portable meters are ideal instruments for environmental measurement. Two temperature models are available: infrared thermometer and dual thermocouple thermometer.
