• The wireless sensor forms a complete boxed unit with the internal sensor probe neatly set into the sidewall of the housing
• The wireless sensor uses an in-built capacitive humidity sensor to detect moisture in the atmosphere

Each sensor comes with a transmitter which wirelessly connects to the main base unit (DATAcentre or MIDIcentre).

The DATAcentre can take up to 120 sensors (wired or wireless) and the MIDIcentre can take up to 20 sensors (wireless only).

Both the DATAcentre and MIDIcentre have a large transmission range with optional repeater modules available, so even when you wheel your dewar away you can be confident it can remain within wireless range of the receiver.

• Convenient with easy sample access
• Single sample retrieval point is ergonomic: no reaching and stretching
• Liquid reservoir below the sample platform can maintain temperature for more than 20 days in vapour use
• Efficient thermal design gives high system surface area enclosed by vacuum
• LN₂ cost savings of up to 70% compared to standard storage units of equivalent capacity are possible
• No extra aids required to lower and maintain temperature - as with some standard tanks
• The HE Series achieves a very low running cost/sample
