INTRODUCTION

This Sper Scientic Pocket Moisture Meter

(model 850001) displays the moisture content

on a large backlit LCD screen. This meter

combines the versatility of measuring many

di󰀨erent materials with the peace of mind

of an in-cap calibration check. The meter

simultaneously displays the moisture content

in multiple formats including percentage, low

and high, and a convenient bar graph that can

be seen at a distance. The meter’s pins are

minimally invasive to surfaces while still having

the strength to penetrate a variety of materials

including hardwoods, brick, and concrete.

FEATURES

• Reads 7 di󰀨erent building materials

• Minimally invasive penetration pins

• Rugged housing

• Hold button for maintaining readings

• Maximum and minimum values

• Backlight

• In-cap calibration check

• LCD that can withstand freezing temperatures

• Reads ambient temperature in °C or °F

• Reads ambient humidity and dew point

• Automatically calculates wet bulb value

MATERIALS SUPPLIED

• Pocket moisture meter

• Calibration cap

• Soft carrying case

• Instruction manual

• Two AAA batteries

humidity of the material being tested.

1. Press UNIT to toggle through temperature

and humidity unit options. The meter will

toggle through temperature settings rst

(°C or °F) followed by the humidity options

of Relative Humidity, Wet Bulb, and Dew

Point (%, WB, and TD).

on the screen, press ENTER to select it. The

meter will return to normal measuring mode.

3. Press UNIT again to toggle to your preferred

humidity unit. Press ENTER to select it. The
