H290D Probe Installation

Standard 100mm / 3.9" probe The standard 100 mm / 3.9” probe is generally not suitable for through wall installation and is designed for full immersion in the environment to be measured. At least 15 to 20” of the probe cable should be inserted together with the probe.
Optional 250mm / 9.8" probe This probe is designed for through-wall installation. To avoid measurement errors, at least 200 mm (7.8") of the probe length should be immersed in the environment to be measured. Probe holder mod. QMA-15 (a flange with compression fitting) facilitates installation of the probe.
