testo 845 – the infrared measurement technology for temperature with integrated humidity module

The testo 845 is a milestone innon-contact temperaturemeasurement. 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.testo 845 is equipped with anoptical resolution of 75:1 for far-field measurements. Surfacetemperatures can be measured accurately even at great distances from the object to be measured. At a distance of 1.2 metres from the object to be measured, the measuring spot diameter is only 16 mm. A crosslaser marks the measuring spotexactly during measurement. Incorrect measurements are eliminated - you always know exactly where you are measuring.The close focus optics allow themeasurement of temperatures onthe smallest surfaces with adiameter of just 1 mm and a distance of 70 mm! Two industrial lasers mark the measuring spot exactly.•Switchable optics for far-fieldmeasurements (75:1) and close focus (1 mm, 70 mm distance)•Especially bright cross lasersighting for indicating the actual measuring point•Reference accuracy ± 0.75 °Cwith super-fast measurement technololgy (scanning 100 ms)•Backlit display (3-line), shows°C, min./max. values, alarm limitvalues and emissivity; in addition display with humidity module: %RH, °Ctd•Optical and audible alarm whenlimit values are exceeded•Instrument memory for 90measurement protocols•PC software for archiving anddocumenting measurement data (included in delivery)•Tripod fitting for onlinemeasurement via USB cable (included in delivery)
