I'm looking for a reliable TSS meter, ideally one that also provides readings for both NTU and TSS. Please include details on the accuracy, range, and any unique features that your product might offer. Additionally, I would appreciate information on pricing, lead times for delivery, and the potential for bulk orders. If there are any optional accessories or calibration services available, please let me know as well. Looking forward to your prompt response!
