I am having salinity issues after being in the hobby for about a year now. My refractometer’s (new and old) are reading wonky. And I have calibrated with 35ppt solution .
For the refractometer only salinity matters right? or am I wrong? I was thinking really simple: 1. Callibrate refractometer with normal 35ppt reaction fluid. 2. Add 1L RODI water in bottle. 3. Add NaCl till my refractometer reads .

This video shows how simple it is to calibrate the RFM300-T and RFM 900-T refractometers from Bellingham + Stanley using calibration fluid.A step by Step guide to refractometer calibration at 2 RI points with video using proper methods & calibration to water and certified fluid.
If there is a discrepancy with the reading and the value you know to be true, then you will need to calibrate your refractometer. The reading error (or tolerance) taken at a set . In theory, if I do his recipe, the NaCl fluid reading should be 1.3394 on the refractometer, and that equates to 35 ppt seawater, right? So, I should make his calibration fluid, put it on the refractometer, if it says 1.3394 ish, I should calibrate my refractometer to 35ppt and then I should be getting accurate readings?
Used with instruments that utilize AG Fluids with temperature compensation like the Opti digital handheld refractometers as well as the RFM700 Series benchtop refractometers. These aqueous solutions include options for 1.33-1.40 RI (0 . I made a calibration solution to Randy's recipe 36,5g NaCl + 963,5g RODI H2O but I'm not sure what next step. If I add a few drops on the refractometer slide will I screw meter to 36.5 ppt or 35 ppt ? Second question . In theory, if I do his recipe, the NaCl fluid reading should be 1.3394 on the refractometer, and that equates to 35 ppt seawater, right? So, I should make his calibration fluid, put it on the refractometer, if it says 1.3394 ish, I should calibrate my refractometer to 35ppt and then I should be getting accurate readings?
Fisher Scientific - Laxco 60° Brix Calibration Fluid for Handheld Analog Refractometer models Shop Laxco™ 60° Brix . 5mL droplet bottle of 60° Brix Calibration solution for calibration of Handheld Analog Refractometer models for brix models range from 45° to 90° .digital refractometer will usually result in more rapid readings and more accurate data (approximately 0). Calibration Calibrating the refractometer is the first step in evaluating sugar content of fruit. It is an easy but often neglected task. Calibration verifies the zero baseline reading, ensuring that subsequent fruit I believe my refractometer is calibrated. I just used the last of my calibration fluid that came with my refractometer to calibrate it. However, I was getting a higher number than anticipated for my honey, so I started measuring other things to see if I could get another point of verification.

Aqua Craft Standard Seawater 35 ppt Refractometer Calibration Solution - 60 ml Brightwell Aquatics Refractometer Calibration Standard, Accurate Reference for The Calibration of Seawater Refractometers, Hydrometers & Other Density I'm seeing a delta of 4 PPT between the two new bottles, aqua craft vs. brightwell solutions. Same refractometer . The recipes are different for refractometers, conductivity devices, and hydrometers. Weighing is better than volume measurement of the salt, if you can do it. For a refractometer: Use 3.65 weight percent sodium chloride solution to match 35 ppt (sg = 1.0264).
Adjust calibration mechanism to read to one of the following specifications: 35 ppt 1.0264 Specific Gravity 1.3394 Refractive Index 53 mS/cm at 25 deg C. Clean and dry prism surface after use. Check instrument calibration regularly, once per month is recommended. Do not add test fluid back to container. Tightly replace lid to prevent evaporation.
The calibration fluid is hygroscopic. This means that if left open the fluid will absorb water vapor from the air and will give erroneous readings. Keep fluid tightly sealed when not in use. Make sure to read the directions for calibration of your specific refractometer. Some of them require a different process for calibration.
