PostSubject: lazer gun or probe    Wed Jul 16, 2014 8:01 am

as ive seen you lot using a lazer gun which is the better to choose from and its getting time that i had one to use heres what ive come up with while viewing price ranges

has been discussed in here though page 2 and 3

http://woodstoves.forumotion.co.uk/t62p15-secondary-air

heres the gun options 550c or the 900c

http://www.ebay.co.uk/itm/Non-Contact-IR-Infrared-Digital-Laser-Thermometer-GM550-50-550-Temperature-Gun-/291073447453?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item43c554561d

http://www.ebay.co.uk/itm/GM900-Non-Contact-IR-Infrared-Thermometer-Laser-Temperature-Gun-Meter-50-900-/390641169571?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item5af40734a3

theres no point with the 700c only a 1.50 difference between them if the 550c is ample enough id rather get that one instead

multimeter is no good to me as i have one already

this one states a 1000c and not bad price either dosnt say if has ktype probe included though

http://www.ebay.co.uk/itm/Mastech-MS8264-Digital-Multimeter-30-Range-Voltmeter-Ammeter-Temperature-Tool-/181437109134?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item2a3e7e938e

http://www.ebay.co.uk/sch/i.html?_sacat=0&_from=R40&_nkw=temperature+multimeter&rt=nc&LH_PrefLoc=1

however if that digital multimeter does come with the k type lead its worth it at 1000c reading for that price more than the gun but gun saves hands and fingers burning but glove is ample enough

ive bought one just went for gm550 model if higher than 1000f its doing its job more so with that heat output

at least i can now test my systems as i build them hopefully will be here by friday

I have looked at a few kiln temp probes with controllers on ebay.

I have no idea which is best but I think a probe possible two or more would be something to consider for testing and development.

i agree a couple of probes whilst testing different builds and during development however the other thing id be interested in getting would be an emissions tester as then could also prove my system is good with that tester

I have got both a laser (900c max) and probe. I think the laser is not as accurate as the probe it is very useful for taking quick measurements in several areas, but the non accuracy is not alway important as you can just compare the temperature reading to each other. The advantage of a probe is that you can drill a hole and leave it in one position and it records higher temperatures. I bought both of men off ebay and they were the cheapest ones.
