Guest guest Posted October 27, 2004 Report Share Posted October 27, 2004 Now that is an interesting thought.... they are one of the most accurate thermometers there are BUT they are designed to remain immersed in what they are testing. As I sit here thinking back to my aquarium days (I've had as many as forty tanks at a time, ranging up to 55 gallons)You have three types of thermometers. The metal ones that hook over the side of the tank, the floating ones, and their sisters that have the little base that sinks into the gravel and the contact ones that stick on the outside of the glass. They are VERY accurate to the tenth of a degree... the key is going to be how to read them quickly enough, before the temp changes.... The floaters (and the sinkers) hold temp the longest when you take them out of the water. I think because of the air inside the glass tuby thing.... The press on ones... I don't know if they go up to 100, I don't remember... Any body else have one or can swing by a pet shop to see... Those take SEVERAL seconds to show temp change.. I think that they would actually hold the reading the longest... but they'd also have to be in position the longest. I'd like to run with this a bit further... As far as when to take a basal temp.... the first morning reading is chosen because, for most people that is the only time that they been total motion free, for the most part.... Not many folks just lay around, not moving, during the day.... Muscle activity creates heat... so, goofy as it sounds, talking can actually increase the temp of the tongue enough to affect the reading. Now... does anyone remember how long you need to be inactive for an accurate temp reading? Respiration and pulse are generally 15 to 30 minutes... but what about temp?

Oh, one other draw back with the tube attached to the metal…the thermometer has to be read as soon as it is withdrawn from the armpit…it starts to drop temperature reading as soon as it encounters a change in atmospheric temperature. I suspect that the tubes that are inside of pressurized air cylinders would hold the temp a bit longer.I'm going to give it a try tomorrow and compare the readings against my old trusty mercury thermometers. I'll let you all know how the comparison temps go… Unfortunately I need the thermometer otherwise I'd break the aquarium thermometer and find out if the stuff is mercury or not…… GossimerP.S. I just ran a night time basal temp and it does work, now to see if it is very accurate in the morning. Quote Link to comment Share on other sites More sharing options...

Guest guest Posted October 28, 2004 Report Share Posted October 28, 2004 Thanks, Jan.... Have you tried one, or know anyone that has.. I'm curious about what folks think... I'm lucky... I still have a good ole mercury one, so I'm okay for now...
