The TV2 fridge-freezer alarm
A two stage alarm alerts you to any unsafe temperature.
- First stage alarm is a local alert on the TV2 monitor:
- Any unsafe temperature turns red on the TV2 monitor;
- Maximum or minimum temperature turns red on the TV2.
- Second stage alarm is triggered when a temperature remains unsafe longer than the user-set delay time:
- The TV2 display beeps and an error message appears with the reason for the alarm;
- Text, Email or phone call alerts.
- Health care clinics
- Blood banks
- Research laboratories
- Testing laboratories
- School kitchens
- Pharmaceutical manufacturing
- Air craft carriers
- Fishing vessels
- Veterinarian offices
Q. How accurate is your temperature sensor?
A. The thermistor sensor is ±0.3°C. (see specifications for accuracy of extreme temperature sensors)
Q. Can I monitor two refrigerators or two freezers instead of one refrigerator and one freezer?
A. Yes the monitor comes with two sensor which are adequate for any temperature between -30°C and 80°C.
Q. Can I monitor more than two appliances with one TV2 monitor?
A. Yes. The monitor had inputs for four sensors.
Q. How difficult is it to install the TV2 refrigerator/freezer alarm?
A. Most users can install it in a few minutes.
Q. Do I need technical help to install the TV2 refrigerator/freezer alarm?
A. Not usually. If help is needed we can supply it via telephone, which is almost always sufficient. If you have a very large computer system you might need some help from your IT department.
Q. Can I see the temperatures on my phone or from my home computer?
A. Yes if you use port forwarding. You might need some technical assistance from your computer guys to do this.
Q. Does the TV2 monitor meet JCAHO, CAP, FDA requirements?
A. Yes. It meets or exceeds all requirements.
Q. Can I monitor a -80° freezer?
A. We have an optional T-type thermocouple which can monitor temperature as low as -200°C.
Q. How far away can the sensors be located from the display?
A. Each sensor has a transmission range of ~60 feet indoors.
Q. Do the sensors have any wires?
A. The wireless sensors have a two foot wire so the transmitters can be on the outside of the freezers.
Q. Do I mount the monitor in the office or on the side of the refrigerator?
A. It does not matter. The monitors can be mounted anywhere they can receive the signal from the sensor transmitter
Q. Do the sensors need to be plugged into wall power?
A. No. Each sensors is powered by a 9vdc battery which has a battery life of ~1 year?
Q. How often is the display updated?
A. Every few seconds. The sensors transmit temperature every 11 to 20 seconds which updates the display.
Q. How often is data logged?
A. Each sensor can have its own data-logging interval. The default interval is every 10 minutes, but can be set between 1/minute to 1/day.
Q. How safe is the logged temperature data?
A. Logged data is stored in non-volatile memory in the monitor. It can also be automatically backed up to a computer.
