Instructions for marine thermometer 1、 Use Marine thermometer is applicable to be installed on pipelines and vessels of marine equipment for on-site temperature measurement. Marine metal sheathed thermometers are also widely used in chemical industry, pharmacy, brewing, printing and dyeing and machinery manufacturing. At the same time, they are suitable for temperature measurement in laboratories and laboratories of various scientific research, education and medical institutions. 2、 Technical parameters 1. Measurement range: - 30 ~ 50 ℃, 0 ~ 50 ℃, 0 ~ 100 ℃, 0 ~ 120 ℃, 0 ~ 150 ℃, 0 ~ 200 ℃, 0 ~ 250 ℃, 0 ~ 300 ℃, 0 ~ 350 ℃, 0 ~ 400 ℃, 0 ~ 450 ℃, 0 ~ 500 ℃ and 0 ~ 600 ℃; 2. Accuracy grade: ± 1 ~ ± 2 division value; 3. Enclosure protection grade: IP44; 4. The thermometer shall work normally within - 25 ~ 55 ℃; 5. Upper body length H (mm): 110, 150, 200. 6. Thread specification: G3 / 8 ", G1 / 2", G3 / 4 ", m20x1.5, m27x2, etc; 3、 Product specification The metal sleeve thermometer is easy to use and reliable in accuracy. Metal sleeves are divided into straight line (WLG) according to shape and material-__ 1(/S)-C），90°（WLG-__ 2(/S)-C）,135°(WLG-__ 3(/S)-C)。 4、 Installation and use 1. The thermometer must measure the temperature according to the specified immersion depth; 2. The thermometer shall be installed in a place convenient for reading, but it shall not be installed on the side or obliquely; 3. The external protective pipe can be directly welded or threaded on the pipeline and container. 5、 Ordering instructions When ordering, the model, measurement range L and thread size shall be indicated. If there are special requirements, they shall be explained.
