Oven controller

Product Introduction: This type of instrument adopts a 24 bit A/D conversion chip from the United States and a single-chip computer control technology with ultra-low noise voltage reference. The instrument has high-precision deviation indication, light column analog output display, ultra-high output resolution, and feedback load stabilization function. Under ideal working conditions, it can achieve control stability of ± 0.003 ℃ and is suitable for use as a reference for high-precision constant temperature bathstemperature controlIt can be widely used in single crystal furnaces, fiber optic production, and the measurement of first and second grade standard platinum resistors. XMTS-71 is equipped with a thermocouple; XMTS-72 is equipped with a thermistor; Other input methods can be used for special ordering.

Network optimization materials:

It is easy to distinguish between open and short circuits, which can be measured using the "× 1Q" mode of a multimeterPrice of professional inspection equipmentIf the resistance value is less than RO, there may be a short circuit; If the multimeter indicates infinity, it can be determined that the resistor has broken. Short circuits in resistors are generally easier to handle as long as they do not affect the length and thickness of the resistor wire,Brand inspection instrument priceFind the short circuit and blow dry it to strengthen the insulation. The repair of a resistor circuit breaker requires changing the length of the resistor wire, which affects the resistance value. Therefore, it is better to replace the resistor with a new one. If flat wire repair is used, it must be verified to be qualified after soldering before it can be used.
