I have a few of these left over from our reef club group buy.

Works very well. Measurement is instant. When you remove it from the water it instantly returns to absolute 0. Doesn't jump around like a Ph Meter.

Specifics:
3 in 1
Thermometer 0~100 degrees F
Specific Gravity 1.000~1.032
Salinity 5ppt~40ppt
Automatic Temp. Compensation

Includes calibration fluid, an extra set of batteries, instructions, and a box to keep it in.

$60 shipped. $2.40 for insurance(recommended)
These sell for $100 plus shipping at M.....depot.

I can accept paypal(230+ verified transactions) or a money order. If you are in Vermont come pick it up. Willing to ship anywere else priority mail.

May have forgot something, if so ask questions.

Just to clarify, the one being sold at marinedepot.com... and all other sites for that matter, is the JBJ Digi-Lab...this is a knock-off of that I would assume?

I also dont know if you are a store or business etc, but it seems that all you do is sell products on various reef sites... usually these forums are designed for members of the sites who contribute TO the sites... I dont know how the admins feel about it here, but I do know that other sites mind.

Just IMO,

It looks like a good product though, do you have any experience with it?

NO this is not a "knock-off". JBJ does not manufacture the Digi-Lab specific gravity meter. They purchase them from the same manufacturer that makes this one and just put their name on it.

You know they say you should never assume...

Could you please tell me how you are supposed to be able to change from C to F temps? I have one and the literature said it would read in either scale but I was never able to figure out how to change it and there wasn't anything in the instructions about making the change. Mine is not marked as a JBJ but looks identical to the one you are showing the pic of. Thanks in advance.

No hard feelings at all. Wish you told me, I would have sold you my refractometer.

Skipm, I believe you have to purchase either in degrees C or Degrees F. The ones I have are in degrees F, how about yours?

Yes, there is a calibration screw that you turn to calibrate it. It comes with calibration fluid that is 30ppt.
