Supported Applications
The Omega RH820 Series consists of handheld humidity and temperature meters designed for portable measurement tasks. The series supports Relative Humidity, Temperature, Dew Point, and Wet/Dry Bulb calculations using an internal NTC sensor or an external Type K thermocouple connected via the SMP type miniature connector.
Operating Conditions & Performance
The RH820 Series operates within an ambient temperature range of 0 to 50°C (32 to 122°F) at less than 80% RH. Storage conditions are specified as -20 to 60°C (-4 to 140°F), 0 to 70% RH with the battery removed from the meter.
- Temperature Measurement Range: -50 to 1000°C (-58 to 1832°F) for external Type K thermocouple; 0 to 60°C (32 to 140°F) for internal temperature sensor.
- Relative Humidity Range: 0 to 100% RH.
- Resolution: 0.1°C/°F.
- Sensor Response Time: 60 sec typical for 90% of Total Range.
Accuracy specifications vary by range and parameter:
- Temperature (External Type K): ±(0.1% rdg +1°C) on -50 to 1000°C; ±(0.1% rdg +2°F) on -58 to 1832°F.
- Internal Temperature Sensor: ±2°C on 0 to 10°C, ±0.5°C on 10 to 45°C, and ±2°C on 45 to 60°C; equivalent Fahrenheit accuracy is ±4°F on 32 to 50°F, ±1°F on 50 to 113°F, and ±4°F on 113 to 140°F.
- Relative Humidity: ±2.5% at 25°C (77°F) for 10 to 90% RH; ±5% at 25°C (77°F) for 0 to 10% RH and 90 to 100% RH.
- Sensor Hysteresis: ±1% RH typical for a 10% to 10% RH excursion.
- RH820: Humidity/temperature handheld meter with internal sensor only (no external data interface).
- RH820U: Includes a USB interface for connection to Windows-compatible software.
- RH820W: Features Wireless 2-Way Transmission operating in the USA, 900 MHz frequency band. The RH820W Frequency Range is specified as 910–920 MHz with low current consumption less than 1 mA and a transmitting distance that can reach 25M.
- RH820U comes with software and a USB cable for wired data transfer.
- RH820W also comes with software but includes a receiver for wireless operation. All wireless units are USA, 900 MHz frequency band versions.
Configuration Options
The series is available in three primary configurations distinguished by interface and communication capabilities:
Standard features across the series include MAX/MIN/AVG/REL/HOLD functions. The unit includes four 1.5V "AAA" batteries, a Type K thermocouple, a rubber boot, NIST calibration (no points), and an operator's manual. Accessories available for the HH800 series family include the SC-800 soft case; the USB model supports the HH800-ADAPTOR AC adaptor.
Key Product Differences
The primary distinction between models is the data interface method:
The device features a 3.5" digit LCD with a maximum reading of 1999 and weighs approximately 265 g (0.6 lb) including batteries. The overall dimensions are 160 H x 83 W x 38 mm D (6.3 x 3.3 x 1.5"). Approvals include CE and RoHS, with a 1 YEAR WARRANTY.
