We require 1,700 prepaid gas meters for a tender project, to be delivered in 3 batches (600/600/500 units). The meters must comply with STS certification and integrate with Customer Interface Unit (CIU). Technical specifications require LoRa-RF communication capability, REST API for remote reading, G1.6 diaphragm type, 3/4" NPTM connections, IP65-IP69 protection, minimum 5-year battery life with low battery/gas alarms. A 10-year warranty covering materials and manufacturing defects is mandatory. Full documentation in English/Portuguese must include calibration certificates and technical compliance proof.

I need a gas analyzer unit capable of detecting multiple gases with specific measurement ranges and sensor types in a single assembled device. Required parameters:
- Hydrogen: 0-50% TCD
- Methane: 0-60% NDIR
- Carbon Monoxide: 0-50% NDIR
- O2: 0-20% Electrochemical
- Carbon Dioxide: 0-30% NDIR
- N2: 0-70% Electrochemical
- NH3: 0-300 PPM Electrochemical
- HCL: 0-20 PPM Electrochemical

All sensors must be integrated into one complete system. Please confirm technical compliance and provide product documentation.

We need to purchase 62 sets of Arduino-based programmable robot kits. The controller should support multiple peripheral connections including buttons, sensors (temperature/pressure/light/acceleration), LEDs, and LCD displays.
