Gizmo Engineering’s temperature alarm shows the tank temperature with the digital display and if the temperature ever gets out of range you set, it produces a loud alarm. The alarm is a 103dB buzzer and stack light, which shows the temperature with the green or red lights.
In addition, the temperature alarm includes a relay output to either shut off equipment with the relay, or communicate temperature events, all in a compact and economical package.
Additional features include: waterproof casing for easy wash down duty; a front button to easily silence the alarm; the buzzer has a snooze alarm that will sound in 30-minutes if pH is not correct; compact enclosure is six-inch by six-inch; and the thermocouple and thermowell are included.

Paul N. Gardner USA, global distributors, producers, and designers of quality physical and inspection instruments for the paint, coatings, and related industries, has introduced a new offering: The compact, portable Sling Psychrometer.
As an easy way to measure relative humidity levels quickly, this uniquely compact Bacharach Sling Psychrometer accurately determines per cent relative humidity without the necessity of consulting complex tables. There is no need to wet the wick each time a reading is taken, and it contains a slide rule calculator which correlates wet and dry bulb thermometer indications for direct reading of relative humidity. When not in use, the thermometer case telescopes into the handle for protection.
The Sling Psychrometer consists of two thermometers that are turned by vigorously swinging the handle and exposing the thermometers to rapid air movement. These two thermometers are called dry bulb and wet bulb. The bulb of one thermometer is placed in direct contact with the room air to measure dry-bulb air temperature. The bulb of the other thermometer is covered with a silk or muslin sleeve that is kept moist to record the wet bulb temperature. Evaporation cools the wet bulb more than the dry bulb, and the humidity is obtained as a function of change in temperature. The atmospheric humidity is determined by calculations, steam tables, or using a psychrometric chart. Gardco.com
