No, INT-21-B is not suitable for use in pressure cooker or microwave oven.
Is INT-21-B suitable for outdoor use?
Yes. The INT-21-B is IP67 waterproof, which means it is suitable for outdoor grilling. In addition, it can last up to 120 hours when used with the base and has a magnetic back that can be attached to any metal surface, all of which makes it convenient for outdoor activities.
What is the Bluetooth connection distance of INT-21-B?
The connection distance of INT-21-B is 328ft/100m without obstacles. Just keep in mind that the phone connects to the base, not the probe, so make sure to keep the base and probe within 19.68ft/6m of each other.
What is the temperature range of INT-21-B?
The INT-21-B probe comes equipped with two sensors, one for monitoring food temperature from 14 to 212℉ (-10 to 100℃), and the other for measuring ambient temperature between 32 and 572℉ (0 to 300℃). For safety use, the alarm will go off when the food temperature reaches 205℉ (96℃).
