to configure:

The host can be connected to temperature probes or temperature wires separately to form a temperature measurement system, which can be flexibly configured according to on-site needs and the number of temperature measurement points (See schematic diagram)

1. The host is a portable instrument equipped with a power switch, lighting switch, socket, and LCD display screen. It can digitally display the measured temperature value and has a night temperature reading lighting function To prevent dust, moisture, and bumps, a thin film touch switch and a strap type instrument cover with good sealing performance are used. The bracket behind the host can also be opened and placed on the desktop for use

2. The temperature probe is made of a plug, wire, handle, and a metal tube with an outer diameter of φ 5mmX220mm. The front end of the tube is encapsulated with a temperature sensor, which is suitable for measuring the temperature of materials and clinker

3. The pre embedded temperature measurement line is made of plugs, wires, and temperature sensors, suitable for measuring the internal temperature of concrete. Each temperature measurement line can measure one temperature point, and temperature measurement points can be arranged arbitrarily during construction For the convenience of layered temperature measurement, each plug of the temperature measuring wire is labeled with a corresponding length specification

Attachment

1. One copy of the user manual

2. One copy of product inspection certificate

3. One copy of quality assurance certificate

5. One nine battery,

Instructions for use

1. Use the host and temperature probe to measure the temperature of the material. Insert the plug of the temperature probe into the host socket, press the power switch, and insert the metal rod of the temperature probe into the measured object. The insertion depth should not be less than half of its length. After about two minutes, read the temperature data on the host When measuring the temperature of the mixture, to avoid excessive impact between the temperature probe and hard objects in the mixture, which may affect its service life, a metal rod can be used to reserve a hole in the mixture first, and then the temperature probe can be inserted into the hole for temperature measurement After each use, the temperature probe should be wiped clean

2. After determining the construction temperature measurement plan for measuring the temperature of large volume concrete using the host and temperature measurement line, select the appropriate length and specification of temperature measurement line according to the number and depth of temperature measurement points. For example, if the actual depth of the temperature measurement point is 0.2m to 0.3m, a 0.5m temperature measurement line can be selected. If the actual depth of the temperature measurement point is 2.5m to 2.8m, a 3m temperature measurement line can be selected, and so on When pre embedding, steel bars and other rods can be used as supports. The temperature measurement line should be tied to the support according to the distance between the longitudinal temperature measurement points, and insulation treatment should be carried out between the temperature sensor and the support When pouring concrete, insert the support with the temperature measuring wire tied into the concrete, place the temperature sensor at the temperature measuring point, leave the plug outside the concrete and cover it 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 temperature, press the power switch of the host, insert the temperature measurement wire plug into the host socket, and the temperature of the corresponding temperature measurement point will be displayed on the host display screen

3. Measure the temperature of winter construction concrete using a host and temperature measurement cable. When pouring concrete, reserve temperature measurement holes according to the winter construction temperature measurement plan, place a temperature measurement cable in each hole, leave the plug of the temperature measurement cable outside the hole and cover it with a plastic bag to avoid moisture and keep it clean When measuring temperature, press the power switch of the host, insert the temperature measurement cable plug into the host socket, and the temperature of the corresponding temperature measurement point will be displayed on the host display screen After each stage of temperature measurement, store the temperature measurement line for future use The temperature measuring wire can also be buried in concrete for one-time use. For specific instructions, please refer to usage method '2'

4. The use of night temperature reading lighting function: When used at night or in a dark environment, press the host lighting switch, and the LCD screen will emit a light green background light, making the reading clear and eye-catching
