The Lyman Digital Lead Thermometer is the safety-first tool for serious bullet casters who need real-time accuracy without risking their hands. Casting bullets means working with molten lead at precise temperatures—get it wrong and you're wasting alloy, getting inconsistent bullets, or worse. This digital thermometer eliminates guesswork with a 6-inch probe long enough to reach deep into even large casting furnaces while keeping you safely back from the heat.
Speed matters when you're managing a hot furnace. This thermometer takes 2.5 measurements per second, so you get instant feedback on your alloy temperature. The large digital display is easy to read from a distance, and you can toggle between Fahrenheit and Celsius depending on your preference or casting manual. The hold button locks a reading on screen—useful for recording temperatures or comparing readings without staring at a live display while standing near molten metal.
Built to handle the extreme environment of bullet casting, the K-type thermocouple probe is rated to 1832°F (1000°C), with accuracy of ±2°F (±1°C) so your alloy is consistently at the temperature your load data demands. One 9-volt battery powers the unit for roughly 200 hours of use, and a low-battery indicator alerts you before it fails mid-casting session.
| Temperature Range | -50 to 1832°F / -50 to 1000°C |
| Accuracy | ±2°F / ±1°C (0.5% of reading) |
| Probe Type | K-type thermocouple |
| Probe Length | 6 inches |
| Measurement Rate | 2.5 measurements per second |
| Display | Digital, switchable F/C |
| Power | One 9-volt battery |
| Battery Life | Approximately 200 hours |
| Features | Hold button, low-battery indicator |
The Lyman Digital Lead Thermometer measures from -50 to 1832°F (-50 to 1000°C), which covers the full range needed for casting lead alloys and monitoring furnace conditions before and after casting.
Accuracy is ±2°F or ±1°C (whichever is greater), with a 0.5% reading accuracy. That precision is sufficient to match the temperature specs in reloading manuals and load data.
The 6-inch probe is designed to work with large casting furnaces and keeps your hand at a safe distance from the heat. If you have an unusually small furnace, confirm the probe will fit; for standard and larger setups, it's the right length.
The thermometer is powered by one 9-volt battery. Check your product packaging to confirm all included items, as some retailers may package accessories separately.
