Price shown is for the HMI41 meter with the HMP45 probe. No more fumbling with charts and graphs, or improper calculations that cost valuable job time. The HM41 Thermo-Hygrometer automatically calculates the GPP (grains per pound) of moisture for you. Suitable for nearly any application, the HM41 is capable of measuring RH at levels as low as 0.1% at temperatures as high as 140º F (212º F with optional HM42 probe). In addition to calculating GPP, the instrument calculates dewpoint temperature, wet bulb temperature and mixing ratio. Various types of probes and custom configurations available. Our in house lab tests have found the HM41 to be the fastest and most accurate handheld thermo-hygrometer available. In addition to providing fast measurements in ambient air, when protected properly, the HM41 probes can be placed inside wall cavaties, subfloors, kitchen/bath cabinets and most other inaccessible areas. Probe Types:
HMP41 relative humidity and temperature probe fix-mounted on the HMI41 indicator
HMP42 for structural humidity measurements from very small spaces (probe diameter 4 mm)
HMP45 with a cable for measurements in ducts and chambers
HMP46 for measurements in high temperatures and places hard to reach Features:
