The thermometer incorporates a 50:1 optic ratio (target distance/diameter ratio), this enables users to measure small targets from a distance. The user stands a safe and comfortable distance from the target, points the thermometer at the surface to be measured, pulls the trigger and instantly reads the temperature. Ideal for measuring the temperature of any item that is difficult to reach. This enables the user to measure most surfaces accurately and quickly.

The SacnTemp RH 860 has an easy-to-read LCD display, with backlight for when ambient light levels are low. The function of measuring temperature, humidity, dew point and wet bulb is ideal for analyzing ambient conditions.

This infrared thermometer measures the surface temperature over the range of -50°C to +1000°C with a 0.1°C or -50 até 1370°C with thermocouple probe. The ScanTemp RH 860 incorporates an auto power off facility that turns the instrument off maximising battery life. This function can be disabled, if required. Each unit incorporates a clear, easy to read, backlit custom LCD display that indicates both the temperature and the emissivity. The thermometer features a four-button keypad, allowing the user to select the mode required, i.e. max, min, differential and average temperatures, view the max/min high and low alarms and adjust the emissivity from 0.1 to 1.0 in 0.01 increments (default set at 0.95).

The SacnTemp RH 860 is five instruments in one as it incorporates a thermocouple socket that will accept a type K thermocouple probe.

To optimize surface temperature accuracy:

1. Determine the emissivity of the object to adjust the spectrum range of the instrument that can be used for measurement.
2. Avoid reflection from other sources of temperature by thermally enveloping the object to be measured
3. For high temperature objects, use smaller wavelength instruments when possible.
4. For semi-transparent materials such as plastic films and glass, make sure that the bottom surface (behind the object) is uniform and below the temperature of the object.
5. Hold the instrument perpendicular to the surface of the object when the emissivity is below 0.9.
6. In all cases, do not exceed the 30 degree angle of incidence.
