WHY HIGH BATTERY CAPACITY IS CRITICAL FOR GAS ANALYSIS
Uninterrupted Field Measurements: Supports extended testing periods for tasks like stack emission monitoring, HVAC system balancing, or automotive emission checks, which often require hours of continuous operation.
Data Integrity: Prevents data loss from an unexpected shutdown during long-term logging of gas concentrations (O2, CO, NOx, SO2, etc. ).
Enhanced Field Productivity: Reduces downtime for battery swaps or charging, allowing technicians and engineers to be more efficient at industrial plants, power stations, or service centers.
Maintains Equipment Value: A simple, high-capacity battery refresh is the most economical way to extend the service life and readiness of your valuable analyzer.
SAFETY, CHARGING & PROFESSIONAL USE NOTES
For Qualified Technicians: Intended for use by environmental engineers, HVAC technicians, service mechanics, and industrial maintenance personnel.
Use Approved Testo Charger Only: Must be charged using the official Testo 350 series charger or docking station. The analyzer's smart charging system is designed for this specific battery. Using a third-party charger is unsafe.
Follow Manufacturer Guidelines: Adhere to all battery handling, storage, and operating instructions in your Testo 350 User Manual.
Calibration & Sensor Health: Ensure your gas analyzer is properly calibrated and that sensors are in good condition for accurate readings. A battery change does not affect calibration.
Proper Disposal: Recycle this professional-grade lithium-ion battery at a certified e-waste or battery recycling facility.
