HM-34 Thermo-Hygrometer

Phoenix HM-34 Thermo-Hygrometer - The pocket-sized Phoenix HM-34 Thermo-Hygrometer makes spot-checking relative humidity and temperature fast and convenient. The HM-34 is accurate, durable and insensitive to dust and most chemical contaminants. Both the humidity and temperature sensors are housed in an extendable probe that retracts back into the rugged plastic casing for storage, creating a compact, easy-to-carry device. The HOLD button allows the user to retain measurements until they can be recorded.
