Multimeter resistance measurement for electric heating tube

Multimeter resistance measurement for electric heating tube

The multimeter resistance file (R*1 or R*10 file) measures the lead wire or lead rod of the electric heating tube. There are two heating pipes or lead rods for single-phase or two-phase. Use the red and black test leads of the multimeter to test the lead wires. The value R indicates that the value is within the range (R=U*U/P, U refers to the marked voltage value of the electric heating tube, P refers to the marked power value of the electric heating tube), which means that the heating wire of the electric heating tube is not short-circuited.

advantages: ceramic heating has the advantages of flexible installation, low temperature resistance, fast heat transfer, good insulation, and manufacturing is not limited by model and size.Commodity structure: The ceramic heater is made of stainless steel skin, and the ceramic with high insulation and fire resistance is put on a resistance wire, and then twisted by a machine to form it, and it can be used when it is turned on.

＊Using ceramic sheet heating, no red light, no extinguishment, fast heating, and can rise to 500°C within 30 seconds.
＊Under 500℃, the nameless fire does not consume oxygen, does not oxidize, and the mouth and tongue are not dry. It can remove the smell of heating pipes and keep the indoor air fresh.
＊The thermal efficiency can reach more than 90%, which is 1.5 times that of PTC heaters and 2 times that of traditional electric heating wire heaters, which can save 30% of power and electricity revenue.
＊It can emit far infrared rays and radiant heat, and its emissivity is as high as 91%.
＊It does not burst when exposed to water, is acid and alkali resistant, and is suitable for use in harsh environments.
＊There is no surge current when starting, and the temperature can be kept at constant temperature.

＊Ceramic heater is suitable for: makeup, face spread, rheumatism, joint pain relief. In addition to room heating and heating pipes, it also has an amazing effect on the cold and sore feet of employees sitting in the office and employees.
＊Use voltage 12V-380V arbitrarily, power 50W-2000W arbitrarily.
*Generally used in household appliances (hair dryer), beauty equipment, medical equipment, industrial dryers, fax machines, etc.
