* Accuracy ±(0.5 °C +0.5% of mv)

830-T3

IR temperature measuring instrument with close focus optics, incl. 2 point laser sighting, adjustable limit values and alarm function, contact temperature probe attachable, incl. battery.

Range -50..+500°C

The fast infrared thermometer 830-T3 is especially suited to temperature measurements on surfaces with a small diameter. A two-point laser marks the measurement point exactly.

* Small measurement point of 2 mm, distance 25 mm
* °C contact measurement with attachable TC probe
* Backlit display
* Audible and optical alarm when limit values are exceeded
* Emissivity adjustable 0.2 to 1.0
* 2 point laser sighting
* Fast measurement value recording at 2 measurements per second
* Current value and Hold value
* Accuracy ±(0.5 °C +0.5% of mv)

The fast and versatile infrared thermometer with 2-point laser marking and 30:1 optics. The surface temperature, also of smaller objects, can be measured at a safe distance. The diameter of the measurement spot is only 36 mm at a distance of 1 m. Possibility of connecting external temperature probes.

* 30:1 optics for measuring temperature at a distance, even on small objects
* 2 laser beams for marking the measurement spot
* Display of current value and Hold value
* Emissivity determination with external temperature probe
* Audible and optical alarm when limit values are exceeded
* Fast measurement value recording at two measurements per second
* Display illumination
* °C contact measurement with connectable TC probe
* Input of upper and lower limit value

831

Model 831, infrared thermometer including belt holder, battery, instruction manual and factory calibration certificate with the measurement points -20 and +80 °C

Thanks to its 30:1 optics, the measuremet spot diameter is only 3.6 cm at a distance of 1 m. This means that even small objects such as yoghurt pots can be easily measured at a distance. Measurement errors are avoided due to a 2-point laser which indicates the exact measurement spot.

At two measurements per second, the 831 is so fast that measurements on palettes or refrigerated shelves can be carrried out in seconds.

* Infrared thermometer with 30:1 optics
* Broad measurement range of -30 to +210 °C
* Backlit display
* Alarm limit values can be set and are optically and audibly indicated
* Including belt holder and factory calibration certificate
* Also available as a set with the core thermometer 106
* 2 laser beams for marking the measurement spot

845

Infrared temperature measuring instrument with cross laser marking and switchable optics for far-field and close focus measurement. Set includes PC software with USB data transfer cable, aluminium case, battery and calibration protocol.

Range -35..+950°C

Infrared temperature measuring instrument with cross laser marking and switchable optics for far-field and close focus measurement. Set includes PC software with USB data transfer cable, aluminium case, battery and calibration protocol. Range -35..+950°C
For the first time, surface temperatures with smallest diameters can be measured accurately at short and long distances. The switchable optics for far-field and close focus measurement make this possible. Measurements in the far-field are made with an optical resolution of 75:1. Surface temperatures can thus be measured accurately even at greater distances from the object to be measured. At a distance of 1.2 metres from the object, the measurement point diameter is only 16 mm. A cross laser marks the measurement point exactly. For measurements at a small distance from the object to be measured, the close focus optics provide a measurement point diameter of only 1 mm at a distance of 70 mm! Two laser points mark the measurement point.

* Switchable optics for far-field measurements (75:1) and close focus (1 mm, 70 mm distance)
* Especially bright cross laser sighting for indicating the actual measuring point
* Reference accuracy ± 0.75 °C with super-fast measurement technololgy (scanning 100 ms)
* Backlit display (3-line) showing °C, min./max. values, alarm limit values and degree of emission
* Optical and audible alarm when limit values are exceeded
* Probe socket for TC probes for determining emissivity
* Instrument memory for 90 measurement protocols
* PC software for archiving and documenting measurement data (included in delivery)
* Tripod fitting for online measurement via USB cable (included in delivery)
* Measurement data documentation on site with report printer
* Aluminium case for instrument and accessories (included)
