The ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The ATC2000 uses a digital PID controller to regulate the application of power to the heating plate to achieve the desired temperature at the monitored sensor. PID stands for Proportional, Integral and Differential. Here’s how PID control works:

ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. Here we will look at how to adjust the basic configuration parameters. From the configuration menu, you can:
- Adjust the set point temperature
- Set the high and low alarm limits
- Enable/disable the audible alarm
- Adjust the three temperature offsets
- Enable adaptive mode and setup the adaptive interval
- Change the shutdown temperature setpoint
You can use the same procedure to adjust any ATC2000 configuration parameter, regardless of which parameter you’re adjusting.
- Press the Config button to access the Configuration menu. Press the Config button again to toggle to the parameter you want to adjust.
- Then use the Up or Down button to make an...more

ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The ATC2000 has three temperature sensors. One is located in the heated plate, and the other two can be plugged into the RTD and TC input ports. The ATC2000monitors all three temperature readings. You can choose which of the three the unit will control. The ATC2000 then heats (or stops heating) the plate to keep the controlled temperature within the alarm limits.

ATC2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. The temperature controller provides electrically quiet control over the heating plate, so that you can place the animal directly onto the heating plate. Here’s how to set up the system.

Needle holders, also known as a needle drivers. They are used in wound closure, ligation, reanastomosis and other surgical procedures which require suturing. The needle is usually held in position by a clamp mechanism, which allows the operator to manipulate the needle through various tissues. The jaws are generally textured and short in comparison to the shank to retain a solid grasp on the needle.

The ATC 2000 is a low noise heating system for maintaining animal body temperature during experimental procedures. Here are five reasons to choose the WPI Animal Temperature Controller. WPI's Adaptive control is unique in the industry, giving you precision control without the need for complex programming when it counts. Simple to setup. Stable control. No local hotspots.
1. ELECTRICALLY QUIET:
The DC heater is extremely quiet in terms of electromagnetic radiation. This is essential in electrophysiological recordings which are very sensitive to electromagnetic interference.
2. PRECISE & STABLE CONTROL:The controller uses proportional, integral, and differential (PID) technology in adjusting the DC voltage output. Compared with switched on/off type controllers, PID controllers provide a much more precise and stable control of temperature. The PID approach is also more immune to the variation of the experimental conditions such as change in animal size and unexpected disturbances.
3. OPTIONS FOR CONTROL:The controller has three temperature sensing inputs that give you options for control.
- The resistive temperature device (RTD) probe input can be used to monitor an RTD rectal probe to control the animal temperature or to monitor ambient temperature, induction chamber temperature or any other temperature.
- When using a thermocouple probe, the thermocouple (TC) probe input can be used just like the RTD input. (TITLE: A T type thermocouple must be used.)
- The heater plate also has an internal temperature sensor. The ATC2000 monitors this sensor to prevent the localized hot spots under animal.
4. ADAPTS TO DIFFERENT SIZE ANIMALS AUTOMATICALLY:Adaptive mode, one of three operational modes, uses the temperature of the heated plate and the temperature of the subject to automatically adjust the PID parameters, regardless of the animal’s size. This approach is less prone to overshoot, but somewhat slower than normal mode to stabilize, depending on the sampling rate used.
5. ELIMINATES LOCAL HOTSPOTS:The plate’s internal temperature sensor prevents localized hot spots under the animal with maximum temperature stability. The Shutdown mode is a fail-safe mode used if the plate temperature ever exceeds your shutdown set point. (TITLE: By default, the shutdown set point is 37ºC.)
