All hygrotest units are configured to customer specification.

From the options below, please select the solution that meets your requirements, for example, a hygrotest 650 with probe on cable, output signal 0 to 20 mA, 150 mm long probe, 8 m long cable, measurement uncertainty 1% RH, open metal protection cage, H6 display, Channel 1: 0 to 45 g/m³, Channel 2: 20 to 160 °C

This results in the following order code:

hygrotest 650 PHT -20/180 / B4 / C2 / 150 / D2 / 8000 / F2 / G4 / H6 / K2 / 0 / 45 / L5 / M2 / 20 / 160 / N1
