The TSI Alnor DP-Calc 8710 micromanometer is a comprehensive measurement solution for industrial hygienists, certification personnel and HVAC professionals who measure pressure, temperature, air velocity and air flow. This innovative instrument features a velocity matrix, auto zero and low-flow accuracy for fast, reliable measurements.

The 16-point velocity matrix of TSI Alnor DP-Calc 8710 micromanometers allow for quick averaged readings per square foot. Auto-zeroing technology eliminates manual zero calibrations between readings. The 8710 is also accurate in low range conditions and features a long battery life (12 hours) and faster recharge time than other available micromanometers.

The TSI Alnor DP-Calc 8710 micromanometer ships complete with carrying case, 18" (46cm) pitot probe, two static pressure probes, two 8-foot (2.4 m) neoprene tubes, user manual, LogDat1 software, serial interface cable, neck strap, internal battery charger, 4 AA NiMH rechargeable batteries, universal AC adapter and NIST traceable calibration certificate.
