The Emerson AMS Trex we received is top quality – solid build, responsive touchscreen, and works perfectly with our HART and Fieldbus devices. It’s definitely made our commissioning and troubleshooting a lot more efficient. Also, big thanks to the seller – very professional, fast shipping, and they knew exactly what we needed. Super reliable supplier. Would absolutely buy from them again.
