Digital Orifice Flow Meter, for HV Air Samplers，Model OFD-1

Orifice Flow Meter Digital Orifice Flow Meter, for HV Air Samplers，Model OFD-1 Calibration at the measurement! Easy & Quick! Flow rate of the high volume (HV) air sampler is calibrated with a root meter. The root meter is a setting type, accordingly, flow rate calibration is difficult at the measurement site. The digital orifice flow meter Model OFD-1 is an on-site use flow rate calibrator of the measurement site for HV air sampler HV-500F/-500R/-700F/-700R/-1000F/-1000R series. This is a sensor type instead of the conventional glass U shape pipe. An atmospheric pressure gauge and a thermometer are integrated in a device, so that there is no need to convert a measuring value at a customer side. Numerical value on a display is automatically used for calibration with HV-R series becomes possible at measuring sites. Features ●Built-in temperature sensor and atmospheric ●The traceability of the flow rate is available. pressure sensor, make it possible to perform flow rate calibration automatically, and display a digital value. ●An option adapter is needed to connect OFD-1 with HV air sampler. ●HV sampler can be automatically calibrated 　(Please purchase the square shape adapter for an connecting through a USB cable to OFD-1. HV-1000F/-1000R/-700F/-700R users, and the round shape adapter for HV-500F/-500R users. ●Preventing the wrong settings, the orifice board When you have an old-model orifice flow meter set, simply use the has an automatic recognition function. accessory adapter for Model OFD-1.)
