    digital pond thermometers

    I need to buy one, i have an infa red one but want another that's for mid depth for a more accurate reading, the infa red one is good but if its windy you get some strange readings..... what are you using? there are some cheapies on Ebay for around £6 with a length of cable you dangle in the pond, any good ? as nice it would be to have one i cannot justify Seneye prices, i don't need a remote option...thanks Steve.

    The inferred ones are great for monitoring variances but they are not overly accurate from what I have found believe itís abound. +-2

    In my Qt I use a cheap prob type, actually come free with my heater. Think you can get them on eBay for about £3



    and they are pretty accurate when I have used my hanna check temp 4 to compare the cheaper thermometer is -.3 out

    thanks, is the .6 difference because the cheaper unit is submerged deeper down in the water column? i assume from your fold up Hannah you can only probe around 6" or so ?

    There the same ones I use. What mike shown cable goes down about 2 1/2feet
    On that one. I buy about 4 at a time.
    Some cables are longer then others.
    Been using them about 4 years now.
    They last between 18 months to 2 years. Cheap as chips

    Itís only - .3 different the photo is with the probe out of the water.

    I would be very surprised if there was any variance in the tank as I have 2 air stones, 1 mid jet a gravity return and Turing the water over every 7 mins.

    I was given the hanna unit would never pay that money if I was buying but it is good to have it to confirm accuracy of lessor units.

    i've got 2 of the cheap digital thermometers can't fault them...
    0.1 C between the two of them, so accurate enough.
    and they are about 10 years old! had them in the loft from my reefkeeping days, just had to replace the batteries.

    i use them in my filter house, one goes through the wall for outside temp. and one in the filters.

    i use a wireless one for the pond but have it tied up, so it's not sitting too low in the water.
    as they can get water in if sitting to low and stop working.
    mine has been fine for 8 months so far....
