Hydrometer Heaters, (gravity sample)

For low gravity oil where the hydrometer gravity test cannot be made without heating the oil sample. Four hydrometer heater models are available. Two models are water heated and two models are electrically heated. The water-heated models come in floor mounted or side mounted. The electrically heated models are floor mounted. The side-mounted model is drained from the bottom and requires no separate hydrometer cylinder. A drain valve is required.
