Why Choose STN Instruments
Accurate Measurement Meter — Certified Accuracy and Traceability
Every unit sold by STN includes a calibration certificate at the time of shipment (batch certificates are provided for single-use data loggers). These certificates document test points across the full measurement range to support the stated accuracy on the data sheet. All measurement data is traceable to SI units through NIST and includes uncertainty values—ensuring measurements with accuracy.
Reliable Measurement Meter — 3-Year Guarantee with Calibration Assurance
All STN units sent back for calibration within three years are covered under our quality guarantee. During recalibration, we provide “as-found” data and assess each unit’s condition. If it cannot be restored to proper working condition, we will replace it with a new one at no cost—complete with “as-left” calibration data, ensuring calibrated performance over time.
