  • Model: WS-1500EL

Product Description:

Product update: this product is discontinued. Please consider the Multi-purpose controller WS-1510ELPM

This is a “heavy duty” sous vide controller that can be used in either homes or restaurants. Compared to WS-1500ES, it has a bigger box and a larger heat sink to handle larger cookers such as  steam tables or food warmers. It can operate at higher working temperature environments with high throughput of food.  
Operating the temperature controller is easy: plug the cooker to the output socket of the controller on the back, drop the sensor into the pot from top and place the cover on,  turn on the controller and cooker, and set the cooking temperature and timer. It will do the rest of the job for you. When finished, the timer will display END and turn on the beeper to tell you the food is ready.
This is the fifth generations of our WS series plug-n-play controller. In addition to the improved heat handling capability and more durable sensor, we also added several new features. A high limit alarm is added to warn user if the temperature is out of control. An open loop alarm is added to warn the user if the sensor is not put into the control loop. On/off control and cooling control function are added for other applications such as freezer temperature control.

This controller uses PT100 RTD sensor. Please click here for the replacement sensor WS-SENSOR08. Another sensor that is compatible with is controller is WS-SENSOR09

  • Plug-n-play unit complete with sensor and power cord. Simple to use.
  • PID algorithm control with one degree precision and stability.
  • Built-in solid state relay for long lasting and noise free power switching.
  • 15 Amp power switching capability that meets the maximum allowed amperage for  household power sockets.
  • High sensitivity sensor constructed with material safe for food cooking.
  • Thin (0.7 mm or 0.030") and flexible sensor cable that allow the sensor to be placed directly in the pot without affecting the closure of the cooker cover
  • Built-in timer that will shut down the cooker and generate a beeping sound when timer finishes.
  • Auto-tune function that can be easily adapted to cookers with unknown thermal response character
  • Displays temperature in either Fahrenheit or Celsius.
  • Thick strong aluminum extrusion chassis that is durable, splash proof, and looks nice on the kitchen counter.
