Used sensors, transmitters and controllers

Consider the type of sensor, its accuracy, range, response time, and compatibility with your existing systems. It's also important to check the sensor's durability and environmental resistance.

Sensors are usually shipped in protective packaging to prevent damage. Ensure that the shipping company is reputable and offers tracking. For sensitive sensors, specialized handling may be required.

Maintenance varies by sensor type but generally includes regular cleaning, calibration, and checking for any physical damage. Follow the manufacturer's guidelines for specific maintenance procedures.
