We use the DH-300 here in Madison and it works well for us. Sample size we use is 3” x 3” which is about the max size. Would be better if one of the other models can use a larger sample size.

Tips-How to do water temperature compensation


Specific gravity of water would be changed along with water temperature,there is necessary to do temperature compensation in base with specific gravity 1.0000 at 4℃ of water.As for water temperature compensation coefficient,this instrument was stored of memory value for 0~49℃.Using thermometer to get actual temperature before testing,then revise the temperature to the one shows up in thermometer.(specific gravity would differ 0.001 if the difference between water temperature is 6℃).Default temperature of this machine is 25℃.Temperature value and other value would be revised by long-press 【A】Key.Here below is detail procedure.

(1) Long-press 【A】till screen display 【C25】

(2) Press 【A】to revise numbers.Press 【ZERO】to shift

(3) Press 【ENTER】to confirm after revise,then get back to measuring mode.
