Synthetic Urine Kit With Warmer: What Is Actually in the Box

What does "kit with warmer" actually include?

The phrase gets used loosely, so here is exactly what is in an Upass 3 oz kit:

A kit without both a heat source and a temperature readout is not complete. You can warm a bottle and still have no way to know whether you are in range.

How does the hand warmer work?

The warmer is air-activated: open the wrapper, and contact with air starts the reaction. Hold or strap it against the bottle on the side opposite the temperature strip so it warms the liquid without sitting on top of the reading. It holds the bottle in the working range for up to 8 hours. Without any heat source, a room-temperature bottle drifts out of range in about an hour.

What temperature should it read?

90 to 100 degrees F, shown by the brightest green segment on the strip. A blank strip usually means the bottle is above 100 degrees F, so let it cool and the reading returns. Full directions are on the official instructions page.

What if I want longer heat, or have no microwave?

Two options. Extra Hot Sacks air-activated hand warmers, the same warmers packed in every kit, bring a room-temperature bottle into range in roughly 45 to 60 minutes and hold it for up to 8 hours, which covers travel and work sites with no microwave available. Or buy a kit that already includes extras: the kits with Hot Sacks included bundle extra warmers for less than buying them separately.
