HH806

Supported Applications

The Omega HH806 series comprises portable digital thermometers with wireless multilogger capabilities designed for industrial temperature measurement and data logging. The device measures external thermocouples of types K, J, R, S, T, E, and N, complying with the N.I.S.T. - ITS 90 standard reference tables.

Operating Conditions & Performance

The HH806 series operates within an ambient temperature range of 0°C to 50°C (32°F to 122°F) at less than 70% or 80% R.H., depending on the specific model documentation. Storage conditions are specified as -20°C to 60°C (-4°F to 140°F). The instrument features a reading rate of 2.5 times per second and input protection rated for 24V dc or 24V ac rms maximum.

Measurement ranges vary by thermocouple type:

• Type K: -200°C to 1372°C (-328°F to 2501°F)
• Type J: -210°C to 1200°C (-346°F to 2192°F)
• Type T: -200°C to 400°C (-328°F to 752°F)
• Type E: -210°C to 1000°C (-346°F to 1832°F) or -220°C to 1000°C
• Type R and S: 0°C to 1767°C (32°F to 3212°F)
• Type N: -50°C to 1300°C (-58°F to 2372°F)

Accuracy specifications are defined as follows:

• K/J/T/E-TYPE: ±(0.05% rdg + 0.3°C) on -50°C to 1372°C; ±(0.05% rdg + 0.7°C) on -50°C to -210°C
• N-TYPE: ±(0.05% rdg + 0.8°C) on -50°C to 0°C; ±(0.05% rdg + 0.4°C) on 0°C to 1300°C
• R/S-TYPE: ±(0.05% rdg + 2°C) on 0°C to 1767°C

Resolution is 0.1° for K, J, T, E, and N types; 1° for R and S types.

Configuration Options

The series supports dual thermocouple inputs with an adjustable T/C offset. Data logging capacity varies by model configuration:

• HH806W: Stores up to 128 samples on demand and 1,024 in logging mode.
• HH806AU and HH806AW: Store up to 256 samples on demand and 16,000 in logging mode.

The device features a triple display configuration with two 4½ digit displays for T1 or T2 and a third 6-digit display for T1-T2 differential or current date/time. Wireless models (HH806W) operate on the 910–920MHz frequency band, while European versions (HH806WE) utilize 868.1–868.5MHz. The wireless transmitting distance can reach 25M without magnetic interference.

Power is supplied by four 1.5V AAA batteries with a typical life of 120 hours using carbon zinc batteries. USB models (HH806AU, HH806AW) include an optional AC adaptor and DC power jack. The unit dimensions are 160mm(H) x 83mm(W) x 38mm(D).

Key Product Differences

The series includes distinct model configurations based on interface capabilities:

• HH806W / HH806WE: Wireless models featuring data transmission via 910–920MHz (USA) or 868.1–868.5MHz (Europe). These units do not include a built-in USB port.
• HH806AU / HH806AW: Models equipped with a built-in USB port and DC power jack for direct computer connectivity or AC operation via the optional adaptor.

The HH806AW model is supplied complete with an NIST certificate (no points), 4 AAA batteries, Type K thermocouples (one per channel), rubber boot, operator's manual, USB cable, wireless receiver, and AC adaptor. Accessories include the SC-800 soft case with belt loop, Windows software packages (HH800-SW for USB models; HH800W-RSW or HH800WE-RSW for wireless models), and a free 1 meter Type K insulated beaded wire thermocouple.
