Response to (OT)Accurate color thermometer recommendation

Accurate digital thermometers are available from chemical supply houses for less than $20. However, just because the temperature of the developer is EXACTLY 68F doesn't mean it's going to STAY that temperature for very long, especially if you are developing sheet film in trays where your hands will continually warm up the solution. Or where the ambient temperature is more than a couple of degrees away from 68F. You may want to consider the Zone VI compensating developing timer. This unit reads the time as if the solution is 68F, no matter what the actual temperature is. Good luck.
