The programmable moorVMS-HEAT skin heater controller provides reproducible heating of skin tissue up to 45ºC to be used with any laser Doppler blood flow monitor, imager or tissue oxygenation monitor. It can also be used as a skin temperature monitor. Assessments include maximal flow response, temperature standardisation. In addition Axon reflex flare response can be performed with the moorVMS-HEAT-HT variant which temporarily allows heating to 47ºC.

The features include;

  • Dual channel: enables simultaneous, independent heating and monitoring of two separate areas.
  • Variable heating rate: independent channel heating rate 0.01ºC — 0.1ºC per second.
  • Stand-alone: manual control enables operation without a separate control unit or computer.
  • Protocol control: to enable fully reproducible procedures in your studies supported by moorVMS-PC Windows™ software.
  • Measurement and analysis software package: automated to aid generation and processing of results.
  • Factory calibrated probes: no calibration necessary for the life time of the probes.
  • Accurate and reproducible: heater range between 20ºC and 45ºC with 0.1ºC increments and a measurement range between 5ºC and 50ºC. Temporary heating to 47ºC offered by the moorVMS-HEAT-HT variant.
  • Multi-channel: combine modules for a multi-channel system with software support for your ideal configuration.
  • Easily connectable: analogue output (0-5V, BNC) and digital (USB) real time data transfer included as standard for connection to data acquisition systems.
  • Reliable: 3 year basic warranty, extends to 5 years with annual servicing (in-built automatic reminder).

This section lists the more common questions our customers have with regards to the moorVMS-HEAT. If you have a question you would like answered that does not appear below then please email us. We are happy to help!


Q. What is the moorVMS-HEAT used for?
A. The moorVMS-HEAT can be used to regulate the blood flow measurement temperature or it can be used to affect reproducible skin temperature changes as a stimulus for blood flow change.

Q. Is the moorVMS-HEAT a stand-alone skin-heating controller?
A. Yes, the moorVMS-HEAT can be used in a stand-alone mode or it can be controlled by moorVMS-PC software. This allows convenient connection of a number of skin heating and iontophoresis modules and full flexibility in the protocol set up.

Q. Can the moorVMS-HEAT be remotely controlled?
A. Yes, the moorVMS-HEAT can be remotely controlled by the moorVMS-PC software, where individual protocols detailing temperature and duration can be programmed.

Q. What is the temperature range of the moorVMS-HEAT?
A. The moorVMS-HEAT has a measurement range of 5-50°C and a heating range of 20-45°C (or ambient to 45°C, if the ambient temperature is greater than 20°C). Important: Ensure the temperature selected is appropriate for the subject to avoid risk of local burns.

Q. Can both channels of the moorVMS-HEAT be set to different temperatures - i.e. controlled independently?
A. Yes, the moorVMS-HEAT probes can be at different temperatures within each time period.

Q. Do you have to have two probes connected to the moorVMS-HEAT for it to work?
A. No, the moorVMS-HEAT will work with only one probe connected.

Q. Do I need to calibrate the moorVMS-HEAT probes?
A. There is no user calibration of the heater probes and new probes are supplied calibrated. We recommend annual factory servicing in order to ensure the system is operating within specification.

Q. When buying new probes for my moorVMS-HEAT, do I have to return the moorVMS-HEAT to calibrate the new probes?
A. No, new probes are calibrated by Moor Instruments without the need of returning the moorVMS-HEAT.

Q. Can I iontophorese and heat at the same time?
A. Yes, use the moorVMS-HEAT VHP2 digit-heating probe in the ION1r Iontophoresis chamber. The moorVMS-PC software allows simultaneous control of both skin heating and iontophoresis protocols.

Q. What optic probes do I use with the moorVMS-HEAT?
A. When using a moorVMS-LDF, you need to use a VP12. For the DRT4 you need to use a DP12-V2 and when using a moorLAB you need to use a MP12-V2.

Q. What adhesive discs do I need to order for my moorVMS-HEAT probes?
A. VHP1 you need to order SHAD.
VHP2 you need to order PAD.
VHP3 you need to order IAD or VHP-FP.

Q. Does the moorVMS-HEAT come with a warranty?
A. Yes, there is a 3-year warranty included with the purchase of a moorVMS-HEAT (the heating probes are covered by a 6 months warranty).
