Hello.  These heaters are described as having “high dielectric strength”, but I cannot find a specific value for this.  Can you please share the dielectric strength?

Asked by: CryoME
Thank you for your inquiry. Standard test is done at 500VDC.

Can we use this heater for a long time? For example, I'm planning to use it for one week to keep my vessel the 300 degrees Celsius.  

Asked by: jhc1
The HDC Heaters are meant for continuous use and using one with the lowest Watt density to meet your requirements would theoretically last the longest.

Is the wire lead covering right next to the heater also able to withstand high temperatures of up to 600 C? I have purchased cartridge heaters before which seem to have some sort of plastic/rubber like coating.

Asked by: tying08
Thank you for the inquiry. Leads are fiberglass insulated UL approved to 250 C. Best regards OMEGA

Hi I purchased both 75 watt and 150 watt heaters - 0250-0125-0075-N-10-1 AND ICH-0250-0125-0150-N-10-1. Why there is contact (75 - 250 M ohm) between the outside sheath and the heater connecting wires. They should be fully insulated.

Asked by: Ajay
Hi Ajay, Yes, heater leads should be isolated from the sheath of the cartridge. Please forward this note to TEMP@OMEGA.COM. Best regards OMEGA
