1、Overview
The instrument is Portable Building Electronic Thermometer is a
pr of es si o n a l tem p era tu re m eas u ri ng i ns tr um en t de v el op ed
acco rdin g to the construction characteristics of my country's
construction industry and relevant technical specifications. It can
displaythemeasuredtemperatureintuitively,accuratelyandquickly,
with good reliability, wide range of use and applications. Warm
operating environment, small size and light weight, easy to carry,
suitable for construction sites and field operations; mainly used for
const ruction, bu ildin g materials, water conservancy, electric power,
metallurgy, petrochemical, ports, roads and bridges, municipal and
otherbasicconstructionprojects.
2、ScopeOfApplication
The instrument is suitable for on-site construction temperature
measurement of various construction projects. It can be used with
temperature measurement probes to measure the temperature of
materialsandclinker,suchas:gas,liquid,fluid,mixtureandgranular
materials; and embedded temperature measurement line. It can be
used to measure the internal temperature of winter construction
concreteandmassconcrete.

measurement The point depth is 2.5m~2.8m, and the temperature
measurement line with a specification of 3m can be selected, and so
on. When pre-embedded, steel bars and other pieces can be used as
supports, and the temperature measurement line is tied to the support
according to the distance of the longitudinal temperature measurement
point. The temperature sensor and the support should be insulated.
When pouring the concrete, implant the support with the temperature
measuring wire into the concrete, the temperature sensor is at the
temperature measuring point, and the plug is left outside of the
concrete and covered with a plastic bag to avoid moisture and keep it
clean. For ease of operation, the length of the wire left outside should
be greater than 20cm. When measuring the temperature, press the
power switch of the main unit and insert the plug of the temperature
measurement line into the socket of the main unit, and the temperature
of the corresponding temperature measurement point can be displayed
on the main unit's display screen.
When pouring concrete, reserve temperature measurement holes

temperature measurement line will be stored for future use. The
temperature measuring line can also be buried in the concrete for
one-timeuse.
