moorVMS-HEAT Skin Heater Controller: Precise Skin Heating for Research Applications

The moorVMS-HEAT Skin Heater Controller provides precise, programmable heating of skin tissue up to 45ºC, ideal for use alongside any laser Doppler blood flow monitor or the moorVMS-OXY tissue oxygenation monitor.

Designed specifically to enhance the reproducibility of micro vascular and tissue oxygenation studies, the moorVMS-HEAT ensures accurate and consistent results with features such as dual independent heating channels and variable heating rates from 0.01ºC to 0.1ºC per second.

Key Benefits:

Dual-channel, independent simultaneous heating and monitoring.
Stand-alone or computer-controlled operation.
Accurate temperature control and reproducibility.
Automated analysis via moorVMS-PC software.
Three-year standard warranty, extendable to five years with annual servicing.

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).
