Getting the right instrumentation
Fill out an application datasheet and send it to Lesman. We'll make sure you get the right instruments for your process.
Sensors
With the expanded product lines offered by Honeywell and Siemens Milltronics, our sensor offering continues to improve all the time. Take a look at Honeywell's conductivity and pH sensors, or Siemens Milltronics new line of capacitance and radar level sensors.
Tired of all the extra charges you pay just to get the exact temperature sensor you need? All of our thermocouple and RTD assemblies are built to your specification, so there are never any "Custom Assembly" charges.
