The Baratron® 690A is designed for high accuracy pressure measurements with single-ended dual electrode/AC bridge instrumentation that is extremely stable and designed to minimize the effect of temperature changes. The 690A operates at an internal temperature of 45°C. By incorporating temperature control into the head, the accuracy is improved to as high as 0.05% of reading.
Features & Benefits:
- Excellent thermal stability due to extremely low temperature coefficients
- Highest accuracy pressure measurement instrument available
- Six decades of measurement often eliminates several transducers with limited resolution
