External upgrades to the unit include the upgraded keypad, power cord clamp, mil-spec paint, and the case has an internal support structure to prevent denting if dropped. The display and microprocessor have been upgraded to operate in extreme sub zero temperatures.
Like it’s predecessor, the H-810BL displays current flow rate, sample time and total volume. The unit can be programmed to take samples based on the user’s established procedures. The functions/parameters established during calibration may be locked in using the keypad security. When the keypad security is on, all keys on the keypad are disabled with the exception of the START/STOP and UNITS keys. The UNITS key will toggle the LCD display from CFM to LPM.
The H-810BL has a two stage brushless blowers that allows maintenance free continuous use. This expanded capability is offered in the same package and footprint as the original H-810.
