Dear Lewis,

I hope this message finds you well.

We would like to formally confirm that the bespoke 170kPa vibrating wire 
piezometers as per your confirmation are fully acceptable in every 
aspect. We sincerely appreciate your continued support and 
responsiveness to our technical requirements.

Your flexibility in providing custom solutions, while maintaining the 
same specifications in terms of lead-time, resolution, performance, and 
accuracy, is greatly valued.

At this point, we are only waiting for the official confirmation letter 
and updated documentation from Campbell Scientific, as you previously 
mentioned. Once received, we will be in a position to finalize all 
technical submissions.

Once again, thank you for your outstanding support. We look forward to 
working closely with you and hope to continue receiving the same level 
of excellent cooperation in the future.

Warm regards,
Sangsan Suebmee

Dear Mr. Lewis Naulls,
Thank you very much for your prompt response.
Regarding the Piezometer, we would like to clarify that the required pre=
ssure range must strictly be between 150&ndash;170 kPa, as=
 specified by the Department of Mineral Resources of Thailand. Of c=
ourse, we would prefer to offer the 170 kPa model, as it is the most suitab=
le specification for this tender. If you are able to calibrate or =
confirm a model that complies with this range, it would be a great support =
for our submission.
I also look forward to receiving the updated technical documentation, es=
pecially for both the Piezometer and the Datalogge=
r, as your support is essential for the preparation of our technic=
al proposal.
Thank you again for your continued assistance, and I look forward to hea=
ring from you soon.

on &nbsp;
Dear Mr. Lewis Naulls,
I hope this message finds you well.
I am writing to kindly follow up on two important matters related to the=
 current bidding preparation for the Department of Mineral Resources.
1. Datalogger Technical Datasheet (Campbell Scientific)=
 We would like to follow up on the updated technical da=
tasheet for the datalogger, which we understand is pending confirmation fro=
m Campbell Scientific. If there are any updates or an expected timeline for=
 its availability, we would greatly appreciate it if you could kindly infor=
m us.
2. Piezometer Pressure Range Requirement Following a thorough review of the project's Terms of Reference (TOR)=
, we would like to clarify a technical specification regarding the required=
 pressure range for the piezometers.
The TOR strictly specifies that the pressure range must not exce=
ed 170 kPa. We understand that Geosense currently offers a 173 kPa=
 model as standard, which slightly exceeds this limit.
Therefore, we would like to ask whether Geosense would be able to supply=
 a custom version of the piezometer calibrated to exactly 170 kPa</=
strong>, while maintaining IP68 protection. This would ens=
ure full compliance with the TOR and bring it in line with alternative mode=
ls on the market, such as Sisgeo's.
If this is feasible, we would kindly request a revised technical datashe=
et reflecting the adjusted specification for inclusion in our submission.</=
p>
We sincerely appreciate your support and cooperation, and look forward t=
o your response on both items at your earliest convenience.
