Key Benefits

 Fast, Reliable Readings

One of the standout features of the Kaiser Lab Tray Thermometer is its quick response time. The thermometer stabilizes within seconds, allowing you to check and adjust chemical temperatures on the spot without delay. This ensures that your developer or fixer operates within the required range—avoiding ruined negatives or prints due to temperature drift.

 Durable & Chemical-Resistant

Crafted from high-quality stainless steel and durable glass, the Kaiser Lab Tray Thermometer is built to withstand frequent use in chemically active environments. Unlike plastic thermometers that degrade over time or digital ones that suffer from corrosion, this model remains reliable even after long-term immersion in photographic solutions.

 Designed for Darkroom Efficiency

The clearly marked, easy-to-read scale is especially beneficial under dim lighting conditions typically found in darkrooms. This makes the Kaiser Lab Tray Thermometer ideal for both amateur and professional setups where visibility is limited and precision is critical.

Calibration & Usage Tips

To ensure your Kaiser Lab Tray Thermometer remains accurate over time, consider these best practices:

• Submerge correctly: Make sure the thermometer is immersed 2–3 cm into the solution without touching the bottom of the tray.
• Let it stabilize: Wait at least 30–45 seconds to ensure a true reading before taking action.
• Use calibration methods: The ice-water method (for 0°C) and boiling-water method (for 100°C) are widely used.
• Routine checks: Calibrate every 2–3 months or whenever the thermometer is dropped or exposed to temperature extremes.
