Description and Specification for Lab Tenders
Astra Scientific Microlance Instant Moisture and Temperature Tester.
Specification: This instrument measures the moisture and temperature of
building materials (such as sand, aggregates and mixes) at depths up to 1
m approx., simply by insertion. The digital readings are shown
instantly. The Microlance has a built-in computer, which gives it the
flexibility to handle a wide range of materials and water contents. The
meter comes with standard calibration for sands and aggregates, but is
easily recalibrated in the field for virtually any material or mixture
using the built-in “Autocal” facility.
Complete with calibration certificate.
