Protimeter Calcheck Calibration Device BLD5086 For added confidence when using your moisture meter, Protimeter has developed this handy calibration device, sometimes referred to as a 'Calcheck'. Used with pin-type Protimeter moisture meters, the user simply touches the pins to the contact points and ensures that their device reads 18%, plus/minus 1%. This tool is supplied as standard with all pin-type Protimeters but, being small, is easily lost or damaged. Product Features: Calcheck device for pin-type meter range Used to check and verify the pin function Readings between 17 and 19% are normal 2 spare 1" needles are included The Calcheck works with the following devices... Mini Digital Mini Timbermaster MMS2 Why check a pin meter at allA resistance meter reads low when contact is poor, and low means "drier than it is" — the dangerous direction for the error to run. A blunt pin, a loose ferrule nut or a worn probe socket all produce it, and none of them announces itself. Touching the pins to the Calcheck takes seconds and tells you the instrument and its pins are still reading true before the figure goes into a report.Related parts Replacement pin needles (BLD0500) Ferrule nuts (BLD0501) Salt calibration check, 75% RH (BLD4790) — the equivalent check for humidity probes rather than pins Meters this fits Protimeter MMS3 — and the MMS2 it replaced Protimeter SurveyMaster Protimeter TimberMaster Protimeter Digital Mini Protimeter Mini C and Protimeter Mini
