Homeothermic Monitoring System
Overview
The Homeothermic Monitoring System keeps mice and rats at a set body temperature during anesthesia, surgery, stereotaxic preparation, imaging, perfusion, and recovery. Choose a 1-, 2-, or 4-channel controller to warm one, two, or up to four animals or procedure positions.
The controller reads temperature from a compatible rectal probe and adjusts heating-pad output around the target temperature you set. Each channel is controlled independently.
How to choose
Pick the channel count first, then the number of pads (up to one per channel) and the heating pad model. The price updates with each choice.
| Controller | Warming positions | Pads you can include |
|---|---|---|
| 1 channel | 1 | 1 |
| 2 channels | Up to 2 | 1 or 2 |
| 4 channels | Up to 4 | 1, 2, 3, or 4 |
Features
- One, two, or four independently controlled warming positions
- Closed-loop rectal-probe feedback
- Seven heating pad sizes, from 70 × 100 mm to 400 × 600 mm
- For mouse and rat work
- Target temperature settable from 10 to 50°C
- 0.1°C display resolution
- Universal 90 to 264 V AC input
- Replacement and extra pads are sold separately
What's included
- One Homeothermic Controller with the channel count you choose
- The heating pads you choose, in the selected model and quantity
- Product documentation
Connector compatibility
The 70 × 100 mm and 120 × 205 mm pads use a 5-pin connector. The larger pads use a 2-pin connector. We confirm that the controller matches your pad connectors before processing your order.

How It Works
The homeothermic monitoring system operates through a closed-loop feedback control mechanism that continuously measures core body temperature via a rectal probe and adjusts heating pad output to maintain set-point temperature. The 1.5mm diameter temperature probe provides real-time thermal monitoring with 0.1°C resolution, while the control unit processes temperature data and modulates heating pad power to counteract heat loss.
The system employs proportional control algorithms to prevent temperature overshoot and maintain stable thermal conditions. When core temperature drops below the set point, the controller increases current to the heating pad; when temperature approaches or exceeds the target, heating is reduced or suspended. Heat insulating pads beneath the heating elements prevent thermal loss to the work surface and improve energy efficiency.
Status monitoring functions track system performance across four operational states: idle mode during startup, warning mode for out-of-range conditions, standby mode for temporary suspension, and normal operation during active temperature control. Audible alarms alert operators to temperature deviations, probe disconnection, or system malfunctions requiring intervention.

Practical Tips
Verify temperature accuracy monthly using NIST-traceable thermometer in water bath at multiple set points.
Why: Regular calibration verification ensures measurement accuracy and identifies sensor drift before it affects experimental data.
Clean temperature probes with mild disinfectant between subjects and inspect for physical damage to sensing tip.
Why: Proper probe maintenance prevents cross-contamination and ensures accurate temperature measurement throughout studies.
Allow 10-15 minutes for system warm-up and temperature stabilization before beginning procedures.
Why: Initial stabilization period ensures the heating system reaches thermal equilibrium and provides consistent temperature control.
Position heat insulating pad beneath heating element to prevent thermal loss to work surface.
Why: Proper insulation improves heating efficiency and reduces power consumption while maintaining more stable temperature control.
Check probe connection security if temperature readings appear erratic or alarms activate unexpectedly.
Why: Loose probe connections can cause signal noise or loss, leading to inaccurate temperature readings and inappropriate heating response.
Set temperature alarms 2-3°C above and below target temperature to provide early warning of thermal deviations.
Why: Conservative alarm limits provide time for intervention before temperature excursions reach levels that could affect subject welfare or data integrity.
Record ambient room temperature along with set point and measured temperatures for complete thermal documentation.
Why: Environmental temperature data helps interpret system performance and identifies external factors that may influence temperature control.

ConductScience provides a comprehensive 2-year manufacturer warranty covering defects in materials and workmanship. Technical support includes calibration guidance, troubleshooting assistance, and replacement part availability throughout the warranty period.
Compliance
What is the temperature response time for the heating system?
Consult product datasheet for specific thermal response characteristics. Response time depends on ambient conditions, subject size, and initial temperature differential.
Can the system maintain temperature during long procedures lasting several hours?
Yes, the closed-loop feedback control is designed for extended operation with continuous monitoring and automatic heating adjustment throughout lengthy procedures.
What probe insertion depth is recommended for accurate temperature measurement?
The 15mm probe length is designed for appropriate rectal insertion depth in rodents. Follow institutional animal care protocols for specific insertion guidelines.
How does the system prevent overheating if the probe becomes disconnected?
The system includes probe disconnection detection with audible alarms and automatic heating suspension to prevent temperature overshoot when sensor input is lost.
What maintenance is required for accurate temperature control?
Regular probe calibration verification, heating pad inspection for damage, and control unit cleaning are recommended. Consult user manual for specific maintenance intervals.
Can multiple units be synchronized for group temperature studies?
Each control unit operates independently. Multi-channel configurations within a single unit provide synchronized control for multiple subjects on that system.
What happens if ambient room temperature exceeds the set point?
The system can provide active heating but not cooling. If ambient temperature exceeds the set point, additional room temperature control may be required.
